They are not related...semes parents took him in when he was young
seems like both were adopted from parents that couldnt have kids.
we know for sure main character is but not too sure about the ML. brother/ml just appeared, but we didnt see him any younger than his 1st appearance (no baby etc, just poof 5 yo) + ML doesnt look like the parents
sooooooo
His Real brother or just Hyung?
