HOLD UP I JUST KNEW THISS??
Everybody gone doin theories before but nobody explicitly mention a related manhwa
(╯°Д °)╯╧╧
There's nothing mentioned that they're twins. Beomjoon is older and he calls Dohyeon little brother

It's been mentioned in the comments section plenty of times
My bad I meant they are brothers not twins, got confused ╥﹏╥
I def missed those... Also why is the linked author's other works not related to that one. I hope someone can edit that too （/TДT)/
They are twins, the little brother is from another manhwa “ Lust (Ryuha)”
