CHA YOHAN (Doctor John): INTP

Introverted Thinking (Ti): INTPs dominant function is their Ti, which allows them to think logically and objectively. Their goal is to be accurate while solving problems. Cha Yohan is shown constantly striving for the correct answer. Like an INTP, he is thorough in his research and analysis, always aiming to be absolutely accurate. He will spend hours of his life thinking and theorizing until he comes up with the answer, even going so far as to neglect not only his needs, but his staffs as well. INTPs seek to understand, which applies to Cha Yohan’s years of studying medicine just to understand what pain is like.

Extraverted Intuition (Ne): Cha Yohan is a brainstormer. Drawing on boards, rambling through meetings, he is always processing out loud. INTPs are known to do this as well. To others, their ideas may seem confusing or wrong even if it actually is logical; the reason most people feel this way is because INTPs tend to hop from one subject to another, looking for underlying patterns or ideas. The reason INTPs are so thorough is because they want the end result to be perfect.

Introverted Sensing (Si): This function helps INTPs remember the information that they have learned. It allows their thoughts to be more structured and put together. Cha Yohan is excellent at diagonising a patient in little time, all thanks to his Si keeping all of the knowledge he has collected. Their assurance that what they believe is absolutely right may come off as arrogant to other people. In Doctor John, Cha Yohan’s confidence in himself caused controversy several times.

KIM JUNGWOO (Swallow the Sun): ISTP

Introverted Thinking (Ti): ISTPs are introverted thinkers, which is exactly what it sounds like. When dealing with information, they process it internally. Because of this, they tend to be quiet people and don’t tend to think verbally. ISTPs are logical and push away emotional matters when solving problems or making decisions. Kim Jungwoo is the same way. He ignores his emotions and thinks through most decisions he makes. They are action oriented, wanting to get things done as soon as possible and move on. ISTPs are difficult to get close to because of these qualities. It takes Soohyun so long to get Jungwoo to open up even a little bit. Like an ISTP, Jungwoo appears cold and mysterious.

Extraverted Sensing (Se): ISTPs are not ones to dedicate themselves long term. They focus on the “here and now” instead of future plans. They enjoy learning about the world around them through their senses and take in information that way. They will try new things just because they want to. Jungwoo tried several new things throughout the drama. He goes to Seoul with no hesitation, works in the US, becomes a mercenary, and eventually works with his father’s company. He risks his life just to feel a different sensation. However, he didn’t do these things without a solid and practical plan behind it. He knew that he would eventually revenge his father and had it all laid out before hand.

Introverted Intuition (Ni): This function is weaker, but that does not mean it is not used. Although ISTPs don’t typically enjoy theories, they will take the concepts or ideas their mind come up with and apply them practically. Their Ni also helps them go by their “gut” instead of overly thinking out their decisions. Kim Jungwoo is usually very thoughtful when making decisions, but he does reach a point where he just does whatever he feels in the moment.

LEE EUNSUNG (New Heart): ENFP

Extraverted Intuition (Ne): ENFPs are always thinking about future ideas and possibilities. They are known to have their “head in the clouds” constantly. Their Ne helps them to detect patterns and jump to conclusions faster. When set on a goal, ENFPs can tend to hone in on one single thing and be very stubborn. Eunsung displays these traits. He is bright and imaginative, always coming up with different and unique ways to solve problems. He also has a tendency to be so determined to fix a patient that he ignores the advice of his superiors and colleagues. However, his quick thinking and ideas have helped save patients many times, thanks to his intuition skipping certain steps in his brain and coming up to the (usually pretty correct) conclusion.

Introverted Feeling (Fi): When making decisions, ENFPs use this function. Rather than being based on emotional feelings, Fi is a feeling that comes from within and helps develop a strong moral code to make decisions by. Because of their Ne and Fi, it is easy for them to go by their “gut feeling”, and let their emotions guide them. ENFPs are very caring and compassionate individuals who are empathetic to the people around them. Eunsung is known to always go by his feelings. He is a very emotional person who places great value on the care he gives to his patients and friends. When he makes a decision, he does it because he truly believes it is the right decision, even if it isn’t popular with everyone else. In fact, he’s usually siding with Chief Choi, who is controversial in the surgeries he chooses to perform.

Extraverted Thinking (Te): ENFPs use their Te to solve problems and come up with solutions. This function helps them think quickly and be more efficient. They tend to balance their thought process by using a decent amount of both their Fi and Te. ENFPs usually “think out loud” instead of internally processing their information. Eunsung is shown to do this. He is always talking and bringing up ideas and scenarios, whether they are bad or good. This is because he processes and understands his thoughts better when spoken out loud. He also is quick on his feet thanks to his Te helping him make fast decisions.

KIM SURO (Kim Suro: The Iron King): ENFJ

Extraverted Feeling (Fe): ENFJs are natural born leaders. They use their Fe to build relationships, empathize with others, and make the best possible decisions for their people group. Kim Suro exhibits all of these. He is generous, understanding, and a fighter for justice and equality for his people. Types with Fe are affected by their environment and can easily point out what needs to be changed. ENFJs will not stop until the flaw that they have fixated on is gone. Suro is the same way, constantly fighting for change in his nation.

Introverted Intuition (Ni): ENFJs are constantly thinking of ways to solve problems. When thinking, they tend to jump around and skip over things in their thought process, which causes them to presume things that will happen. ENFJs are more comfortable trying new things because they use their Ni to mostly correctly predict the outcome. Throughout the drama, we see Suro constantly trying and succeeding at new things. He builds a ship with no experience, builds and runs an iron forge, and eventually becomes king. He is confident in his decisions because of his Ni assuming that he will be successful. ENFJs are also excellent with people, using their Fe and Ni to naturally empathize and point out people’s dilemmas. Suro is known to do this, easily understanding his friends and acquaintances’ feelings. 

Extraverted Sensing (Se): As mentioned earlier, Suro loves to try new things. A well developed Se makes ENFJs crave to experience different sensations. Se can help ENFJs organize their thoughts in a more understandable way. Suro’s Se strengthens as he ages. He uses it to create a solid, well thought-out plans and helps him to also focus on the smaller details instead of just the bigger picture.

SHIN SEGI (Kill Me Heal Me): ESTP

Extraverted Sensing (Se): Unlike Cha Dohyun, Segi longs to be constantly entertained. Being a sensor, he learns about the world around him by his senses. ESTPs don’t want to just learn about something; they want to experience it hands on. Segi searches for new thrills each time he comes out. ESTPs are also known to be bored by situations that involve a great deal of concentration. This is why Segi struggles so much by trying to fill in Dohyun’s role at work. At heart, he is just a little boy who wants to have fun with Rijin.

Introverted Thinking (Ti): Although it may seem out of character to other people, ESTPs can be very goal oriented. As shown in the drama, Shin Segi is very determined to get rid of Cha Dohyun. ESTPs also use their Ti to master skill sets and come up with logical and practical solutions to problems. Even though Segi looks to be acting irrationally, his brain has decided that the actions he performs are the most logical for him.

Extraverted Feeling (Fe): This function is used while the ESTP is socializing. They use their Fe to create good relationships and harmony in their friend groups. Shin Segi does act like he doesn’t need anyone, but that is not the case. ESTPs long to be surrounded by the people they love. Segi, an immature ESTP, will sacrifice others’ wants and needs to satisfy his own, but a more mature ESTP will go out of their way to create a safe environment for the people they are close to. Segi rarely shows this, only when he is with Rijin. ESTPs don’t typically talk about their emotions, which can cause them to boil over. Segi has had this problem numerous times throughout the drama. ESTPs need to surround themselves with caring individuals to help bring their emotions out in a healthy way.

CHA JOOHYUK (Familiar Wife): ESFP

Extraverted Sensing (Se): ESFPs live in the here and now. They explore and understand the world by using their senses. They love to have fun and are always looking to be entertained. Cha Joohyuk displays the same traits. He wants a new video game consol, he wants a new wife, he wants a new environment. Joohyuk is constantly looking for new ways to satisfy his thirst for fun. Like ESFPs, he does not plan well for the future and can tend to be reckless in his decision making. Joohyuk also does not like routine, which is why meeting with Hyewon’s parents every weekend or working everyday become boring to him.

Introverted Feeling (Fi): When making decisions, Cha Joohyuk rarely thinks. He is always deciding based on his feelings at the given moment, which can cause bad decisions (aka switching your wife). However, this does not mean ESFPs are entirely selfish. In fact, it’s habitual for them to bulldoze over their feelings to please other people because of their fear of confrontation. Throughout the show, we see how much Joohyuk dislikes confrontation, from the arguments with his original wife to his best friend punching him in the face. ESFPs are empathetic and warm to the people they love and cherish. In the end, Joohyuk is shown to care deeply for his family and friends and makes everything right.

Extraverted Thinking (Te): When ESFPs strengthen this function, it is used more during their decision making. They use this function to solve problems and create order in their environment. Because of their fear of upsetting others, ESFPs tend to rarely share their ideas. In Familiar Wife, we rarely see Cha Joohyuk use his Te because of how often he goes by his feelings. However, we see in the flashbacks how smart Cha Joohyuk was in college. In fact, he became Woojin’s tutor because of his excellence in school.

JISUNG: ISFJ

Introverted Sensing (Si): From watching interviews to reality shows he has starred in, anyone can tell that Jisung is very detailed. For every role he takes, he prepares thoroughly, remembering the information he learns as he acts out his scene. ISFJs are always very observant to their environment, especially the people surrounding them. Several interviews from people close to Jisung will show that he is very attentive and observant to the needs of others. Jisung is known for having a good memory, always ready to take a stroll down memory lane. This is also a common ISFJ trait.

Extraverted Feeling (Fe): ISFJs are people persons, always serving others and trying to keep the peace. Jisung has always been known to be considerate, generous, and caring with everyone. Like a true ISFJ, Jisung has opened up about learning not to give too much of himself to please everyone. This only happens because of the deep emotional connections he feels with his coworkers, friends, and family. He is always very open about how much he loves and cares for his wife, children, and peers; he has even shed tears on television because of sweet messages sent to him from his castmates. He is an emotional sweetheart!

Introverted Thinking (Ti): ISFJs are organized planners who like routine and order. This function tends to strengthen as the ISFJ grows older. On RunningMan, we see that Jisung has a high IQ score. He is a curious thinker who loves to be intellectually challenged. Watching his first appearance on RunningMan, I can tell how much Jisung enjoyed putting the pieces together and finishing the puzzle. His Ti function has definitely strengthened.
