Beomjun Cha. Older brother from the Lust comic.
Lust comic? Ive never read tjisss but i dont think its on this site
https://www.mangago.me/read-manga/lust_2/
They're not linked. Enjoy! Beomjun makes a small cameo towards the end.
wait but how do you know it's the same character if both stories are not linked? is it the same author? because if so then wouldn't that be a huge spoiler to this manhwa since he's a cop or something in the other one? we'll know for sure that he's undercover here if so (I haven't read lust but i checked the last chapter and that's what i got from it. he does look like mop head but kinda a bit different so idk)
By chance did you find out if it’s really him from lust ?
I checked out the link and it looked like they have the same name and look similar. So it's most likely him
Did we ever find out curly haired top guy name or was he walys jsut perm ahjussi
