why does ido bang on the door and acts like he cares now?

Ido loves him but after the omega betrayed him he's hurt and can't trust him. They don't talk it out. Ido thinks that the omega doesn't love him. It's all a fucked up misunderstanding that none of them think of telling the other the truth and with everything happening its making it worse

oh oki i see, then maybe ido should try to explain himself how he really feels, it´s not like he ever told sejin that before sejin betrayed him either.
