#suu won

This means that this freak's people have obtained the blood of dragons, the source of their power

and does he really think he has Suwon in his hand?

I am also wondering after your question and maybe because Jeaha unraveled Haku right away. He was reading Haku like from a book in Awa when Yona passed the test. He perfectly read Haku's feelings and relationship with Yona. I think Jeaha knows people well and he knew what Haku was like after getting to know people so briefly. Jeaha is honest and loyal and genuinely supportive, and so is Haku. Their relationship is not artificial, but real and, above all, sincere.

I think Suwon didn't know Haku as well as Jeaha, he always idealized Haku. I know their bond is strong and can see it even in the present chapters, but they were both distant and not honest with each other. Suwon sees in Haku a goal that he must overcome.

Their relationship was also not honest. Haku hid his sincere feelings and he. They both distanced themselves from each other, even though they had been friends since childhood. Even though they have a strong bond, their relationship will always distance themselves from Haku and Jeaha.
