I will say, not very fair to assume someone can't move one. Like, duh he didnt think of you as more than a bff when; 1- you also never said anything, and 2- he thought he was going to be with someone else. You don't know what he would've done had he known your feelings before returning to Korea. You could see his affection since they were first introduced. But the again, Seojoon is blinded by jealousy and heartbreak so i guess he wouldn't be thinking farther than "he already loved someone else so he can't possibly fall for me" I feel like that's just how love and relationships work. You find someone, fall in love , and sometimes that doesnt work out so you breakup, heal over it and start again. But i'm also psyced to see the next chapter
