[Title] pls help

I remember it was a college webtoon and the ML was like a badboy stereotype, had tan/dark skin, black hair, with a tattoo on his forearm. Memory of the FL is hazy, either blonde/brown hair, light skin.

Their relationship was similar to “childhood friend complex” except they drifted apart growing up?? Anyway I don’t really remember how they got back together but at one point the FL introduces ML to her parents and I vividly recall him covering up his tattoo just for her. Idk😔😕 (also they once did it in his car)
