I'm not sure about that .. they said that that's mr kitty's brother and that he has his own story which is what Eerie6x commented. Someone also said this: "Cha beom only appear in the last chapter of the main or side story. And it doesn't say they are twins, they are 3 siblings, Cha is the oldest"
Actually second the eldest
I don't remember well. I know their father say the youngest is disappointment to the family lmao I wonder if he gonna have his own story, cause until now he didn't appear in any of the stories. But making the brother exactly like him was kinda meh, in lust he is different, straight hair and such.
The eldest (unnamed and did not make an appearance) was said to have taken over the company. Second to the eldest is Cha Beomjun (ML) then Dohyun is the youngest. He relayed his backrground in chapter 48 of Lust and on the chapter where Beomjun made his appearance, he said that Dohyub was his one and only little brother.
Brother of Mr. Fluffy? The red hair's possibility of being bottom? Wth HAHAHAHAHAHA
