I'm fairly sure he'll get into a relationship with the sunbae but won't be able to forget Woojin's dick and run back to him (as someone has mentioned chances for a cuckolding scene just skyrocketed)
If Taeju truly wanted to get out of Euihyun's life he'd have had to travel to the other side of the world, but even that probably wouldn't be enough to keep him from running to his side
I'm actually pissed that Gun is fighting for that wrinkly rat, even willing to die for him and the only reason for that is that he asked him to be his bodyguard? I thought it was gonna be something deep
they could never make me like you Leo
