HELP

someone help me! i can’t remember this manhwas name or general plot, i just remember that there was a group of 3 people, two guys and a girl. one of the guys was the ML, the other guy was tannish with short military like hair. the girl had a crush on the ML but that was never gonna happen. anyways the three of them were like siblings, they grew up together and stuff. the big plot twist is that the two boys ended up trading names, because the guy with short hair was being pursued by his family when they were children, if i remember correctly the short haired guy liked the girl, this may be a false memory but im pretty sure the ML had black hair and a wolfcut. it was romance but i cant remember the FL, hell it may have even been BL for all i know.
