Long ago I read a 2-volume story about a girl playing a card game (which looks like poker I think). The girl is the daughter of a famous poker player, and used to accompany her father to casinos when she was small. Due to her tomboy look, people thought she was a boy. Then her father mysteriously disappeared so she stopped playing and grew up like a normal girl. Later she decided to come back to rescue her close friend, and so the story began... There was also a gangster who was a friend of her family and he became her lover in the end...

I'm not sure if this is a manga or manhua coz the art looks a bit Chinese. Does anyone know its name?
😕

Thank you very much 😃
