2 things.
1. Luke misunderstands what Bruno did wrong, like it's a complete different issue from locking him inside. So when he hears Bruno say that Andrew said Luke would never forgive him, Luke feels like Andrew is trying to distance him from his friends.
2. Luke knows that Bruno locked him up but doesn't think he is still working with that asshole and wants to hear him out. Bruno says what he says and Luke feels that the issue that was brought up before is bigger than he thought. Which is the Andrew sees him as someone to protect and not someone to communicate with. Therefore their relationship is imbalanced.
On a side note, I don't really think anything bad is going to happen between Luke and Andrew. Luke really likes hearing people out, he did it with Stacy and know with Bruno, so I trust he will do it with Andrew. However, Luke is also stressed out and Andrew might not be able to express himself properly but I don't think it'll turn out like that.
AHH IMMA PULL OUT MY HAIR ITS SO SAD THAT THEY DON'T UNDERSTAND EACH OTHER Like no one mischaracterizes Juheon and Dohu more than each other.
Juheon on one hand sees Dohu as a shallow person who never has anything important. This is in part because Dohu himself never opened up about it. Dohu was completely mistreated by the people around him and sees himself as inhuman. He doesn't understand what he feels but he showed it through his actions. But without communication his actions alone weren't enough to prove to Juheon that he loves him. Because of that Juheon has a messed up perception on Dohu as a person. He already villianized Dohu and sees him as a regret.
On the other hand Dohu doesn't truly and I mean truly understand what Juheon felt when he discovered the truth. Dohu again has trouble understanding his own emotions much less other people. He knows superficially that what he did would upset Juheon but he didn't know the extent because again Juheon also failed to completely open up about his worries and past. Dohu doesn't understand that for Juheon he was the only person that liked him and his flaws and that in his mind did it with no ulterior motives other than love. So he doesn't understand the betrayal that he felt. Writing the novel based on Juheon might not seem that serious but it was a catalyst that showed the true problem: Juheon wanted to be loved because of who he is not what he can give.
These misconceptions and misunderstandings that they have towards each other only grow as the years passed. Dohu most likely doesn't understand the true reason why Juheon is upset and instead believes that what upset Juheon is the same reason why other people don't like him. He has fundamentally changed from the person he was in college, he had become more conscious of himself despite not outwardly showing it. Why? Because he truly love Juheon, and his opinions Abt him affected him more than whatever the other people thought Abt him. So he changed and it seems like because he has changed what other people found frustrating Abt him superficially, he believes that he can now pursue Juheon again. Meanwhile, Juheon still sees Dohu as his college self. Someone who doesn't care what others say and does what he wants. He sees Dohu's actions as him just doing what he wants all over again without changing.
I'm just throwing out my ideas and analysis on the characters.






I have a prediction that one of those dates will be riding a bicycle since they never filled that promise as far as I remember.
