What would you have done when your long life crush that never even payed attention to you and now you're tired of being hurt and third wheeling and leave and now the guy gets rejected and you who's trying to move on just shows up saying he's willing to have a fake love like who wants that??? That will only hurt more if you ask me. And seojoon knew blondie had a crush on someone else that's why he didn't say anything that will only ruin their friendship that's how willing he was to even stay just by the Blondie's side but now that he saw clearly he never had a chance with blondie he didn't want to be hurt anymore what's wrong with that??
Seojoon was the selfish one??? What??? Are we even reading the same thing? Blondie was the selfish one he doesn't know when to let go even though he's the one who's caused all of seojoons pain he doesn't even understand that he's probably hurting seojoons feelings just by saying he's just gonna agree dating seojoon just to have his assistant back cause dating is a serious thing and seojoon knows that cause he's probably a perfectionist and mature
I'm not saying blondie is mean though cause he was probably loyal to boss from childhood and seojoon knows that, and that was probably why he stayed quiet and let blondie figure out his feelings but now that seojoon knew he didn't had any chance, why chase after someone you already know you probably
don't have any chance with and will probably hurt you if you stayed???
Like I said he knew that blondie liked boss at that time and probably thought that being beside him is enough though that was coward I understand seojoon tho cause even if he did confess you know how that would turn out cause like blondie was already committed to boss at that time and even waited for years just for blondie to meet boss again even though there might be a chance boss might find love before he can even meet him and seojoon knew that cause of how clever of a man he is and tried to show how he loves and cares for blondie through his actions alone no words just acts
Okay yeah he wasn't obligated but I didn't say he was tho, but like you saw how seojoon was already trying to move on by moving away and now blondie is back he just simply says "Ill date you if you want" that probably hurts for seojoon cause seojoon doesn't want joke of a date he wants to feel true love like what that diva said (I forgot her name lol) and just simply saying "we'll date just come back" well not that exactly but that's basically what he said and notice how that literally sounds like blondie is forced instead of willing?? It shows how or sounds like blondie doesn't even loves him as a romantical one yet

No way they are blaming blondie when the other one said his shit and run away lmao the audacity.... blondie deserves better lol the other is a coward who didnt even try to win him over
