UGH

Woojung and Seohee truly deserve each other. Both are selfish as*holes. Stop blaming others and fix yourselves first!!
Just because some readers choose to focus on these characters' potentially redeemable qualities, it doesn't negate the facts of their cruelty, homophobia and their disregard of others.
No, Woojung, your "sacrifice" for Seohee's happiness isn't really that. He knew very well that Jinwoo wouldn't come to like her and Seohee would end up even more hurt, yet still kept forcing him to go to her. Why? Cause he's afraid he'd lose her completely if he tried to reason with her toxic behavior and hopes he'll eventually become the knight in shining armor who'll comfort her.
Seohee, darling, learn to accept other people's decisions and stop trying to manipulate them to get what you want.
