Yet the same professor use work for leading the uke (his student by the way) into his house when he's in rut and make a move on him. If it's not being manipulative I don't know what it is ? Wooju is younger than him too.
People find Jiheon annoying because he's manipulative and obsessive which I do understand yet I don't know why the same people still choose Mr. Cha when he's unprofessional and manipulative.
I understand if it's a matter of preference. But both ML are very flawed and annoying in their own way. What put Sunjoon in a better spot than Jiheon is because Sunjoon move forward the story. So in this situation as a character he's better. I do agree with you that Jiheon needs to work on himself if he wants to be with Wooju. Both of them are so immature. They're the worst match in the beginning of the story.
No worry ! I can understand why Sunjoon "bad actions" in the story doesn't stand out much because Jiheon easily act as a red flag so if you put a character like Sunjoon next to Jiheon... Eventually you'll remember better Jiheon wrong doings rather than Sunjoon... Also Jiheon is always with the MC so Jiheon have more interactions than Sunjoon.
Sorry yall, but blondie is annoying, he can't just control reddies life, and also, reddie doesn't know much about blondie and it just feels like bad relationship. Professor, I'm w u
