You're not crazy. I also think that's actually what's going on.
I think he's been crushing on him since they met, but never said anything because he was straight & now that he found out he's bi, he picked the weakest target to try & break them up.
Exactly my thoughts!!!!
I have another crazy theory!! sorry, I woke up with a vivid imagination, even doesn't make sense
What if the first crush of Doyeon is Daehyun and he likes him and wants to boing him in every part of his apartment?? And he returned to Korea to get him and why not? and he can learn he is bisexual so his fantasy is completed.
