i forgot the name of a 망가 series

summary: as far as i can remember, its about this boy (can’t remember the name) who got into trouble with some mafia 또는 gang of some sort and he’s now on the run with his (possibly older) brother and his brother’s girlfriend

notes:
- this 망가 series didn’t have an 아니메 adaption so it’s harder for me to find
- the art style was 더 많이 realistic than others and didn’t have the classic 아니메 eyes
- i remember the girlfriend’s haircut being very y2k themed
- the main character (the guy who is on the run) had black dark hair as well as his brother and i remember the mc possibly wearing a white tank 상단, 맨 위로
- i don’t think it’s a very 인기 망가 series either, not sure if that’s helpful tho
- i remember the first few pages being coloured
- the name of the series might be something like “my baby” 또는 “my sweet baby” but i haven’t found it 의해 searching that up so i could be wrong
