I feel like I'm missing an important piece of the story here. So, did Seonho save Dukgwang by asking his father to forgive the psycho sunbae? I wish there would be some sort of explanation on how the knife ended up being sent to Dukgwang.
Sleeping around is about the mildest thing he can do. It's not like he was boyfriends with the uke at the time. I'm not saying it's okay to do that. I'm just saying that the guy's a yakuza. Don't expect him to be a good guy just because he's in love with the doctor.
I waited a few years to continue reading this but I'm surprised the story hasn't progressed much.
