I'm trying to find I guess it was shoujo manga plot was about yakuza girl who got her bodyguard some ikemen boy who was in love with her when he was yough she protected him and he decided to become strong and help her lead her clan however they cannot fall in love as they are only bound together by their (body tattoo - I think it was on their back) of lilith or rose not so sure please any links which would lead me to this manga are appreciated (⌒▽⌒)

I read this manga but I forgot its name heeelp! TwT so the manga I´m trying to find is shoujo one, the main char was one girl who attended cram school where her cousin worked as teacher, he always gave her lift from cram school to her home, then one day she was chatting online trying to find "boyfriend" and that angried him, so he confessed to her, but she didn´t see him as man so he took her for first date they went to swimming pool and he teased her "to pretend they´re couple" later on she fell for him x3

I´m trying to find this one manga as it was only short story and if I remember right it was added to one oneshot manga so it became quite difficult for me to find it ヽ(`Д´)ﾉ

Any info about this would be appreciated ヾ(☆▽☆)
