I am surprised by how many people failed to understand why ir hurted juhyeon. I am not sure because i have similar life or that we are both infj:
WHAT JUHYEON wanted wasnt love. It was to be SEEN as who he is. He thought that Dohyun saw the real and love him. He thought thats why dohyun chased him,not because personal agenda.
İn my opinion Dohyun had a crush since the beginning and fell in love before juhyeon. He fell in love with real juhyeon by getting knowing him.
But from juhyeon s perspective, he doesnt know. No. He cant believe that mc actually loved himvas character or as person. This is something even mc wasnt sure until very later. You all need to accept that Dohyun was very selfish with his decisions. He didnt care enough to reveal the truth because for him, it wasnt a big deal.
But for juhyeon, it was everything. It was the reason he started liking mc. "Oh this selfish guy is actually interested in me as person?!!!" bathump batump. I was waiting this drama since chapter 1. Because Dohyuns character needed arc about learning emotions, his own emotions and that he need to put others first sometimes. That he cant live selfish like this because his way of thinking is hurting people, person he loves. And being seen as "who he is" is literally center of juhyeons arc. Because he had to fake emotions all the time. He is not even sure himself which part of him is real. He feels like noone really sees or understands him. For him, being understood is being loved. And that is something Dohyun failed to do, even though Dohyun didnt mean it but it is something he needs to learn.
This drama is what makes their story as lovers and characters as interesting. And i hope we explore this more.
