The second couple

He can’t control that his Bestfriend never told him he liked him. He did say he didn’t pay too much attention to him (not even knowing his preferences) but, at the end of the day, you can’t punish someone for not knowing something no one told them.

If you want to confess to someone, then confess; if you hide it you can’t be mad they pursue someone else and never acknowledge your feelings they don’t know about.

He was in love with someone else so he’s not going to try and look for other people that are in love with him; it’s really easy to miss those signs. And if you’ve ever been confessed to by a friend it’s really easy to have hindsight into the actions you just thought of as actions done but a friend.

Deciding to drop a love bomb on someone who only considered you a friend because they were pursuing someone else one you KNEW they were in love with, then running away (literally quitting and hopping a flight, using his job against him so he can’t have a conversation with you) is Cowardly.

Idk. They were friends. If he cared about his friend (I mean he does but he is more of a spoiled friend, who doesn't do much or give attention to that friend and just takes - like how a child would just take and not appreciate their parent that much), maybe he would have noticed. Not in an instant but he might have been weirded out or wondered why his friend is so dedicated to him, or notice when he blushes or looks away.

Blondie is quite self absorbed. He sees himself or his target (of affection) and nothing else - regardless of how he affects others. Tbh, in any situation, lovers, parents, workmates - if someone who gives their all, to the point of being a pushover, reaches their limit, they can just go. Call them coward but they just had enough of someone who will not look their way, even out of just being appreciative.
