Haru coining the term “Extra-Ordinary You” to describe Dan Oh was such a beautifully poignant and meaningful moment. On one hand, because she was the one who named him first which means that now the Korean title for the show reflects the name she gave him, while the English title refers to the moniker Haru came up with for her. On the other, because from the moment Baek Young became self-aware he’s been using the word “extra” as the ultimate insult to Haru, and both directly and indirectly to Dan Oh, which is much worse than calling him any other vulgar name because by labelling him a “mere extra” Baek Young belittles his very existence as insignificant and almost useless, basically questioning Haru’s right to live and suggesting his sole of his existence is to serve others (how damn symbollic of Haru’s and BY’s Goryeo counterparts). 

BY makes it sound as if being an extra were something inferior and dirty. It’s something that really troubles Haru and not so much for his own sake as for Dan Oh’s because he’s heard her multiple times calling herself an “extra”. So when he coins that “Extra-Ordinary You” nickname name he is basically turning BY’s insult of her into a precious endearment, something truly special and singular. It’s not about your set-up in life, it’s about how you use the time you were given and live it to the fullest. It’s no wonder Dan Oh ended up falling for Haru; because even if you take away the whole “past-lives-lovers” scenario, he is the one person who treats her as if she were the main protagonist and he were her most devoted fan.

“I would have killed him if I were her, too.”
