If we find out he didn't go back and save the wedding cabinet than he really is irredeemable trash because that's the bare MINIMUM of making anything up to Dan
I'm pretty much a million percent certain he kissed that guy in high school knowing yungwoon would see it, it was a toxic test just like everything he's doing now
Instant tears when the dad asked if he was his boyfriend then sobbed when he said he can always tell who his son likes then uncontrollable sobbing that he'll love and accept his son no matter what and he's been waiting for him to have the courage to tell him.
Honestly, he's not suffering enough.
