I have only seen like one panel of it
It's in uni setting , so this blond guy , a playboy apprantely who had dated like 5 people, is flirting with a black hair guy who has never dated but have hooked up a lot.
They are in a classroom and the blond hair guy is flirting with the black hair guy who is nervous because he has never been hit on.

Fl is very beautiful she was married and had a daughter. Her husband dies and her daughter went missing and she's being forced to be an count's mistress. Then one day when she is being dragged out of her house by the count and his guard ml comes there , he is maybe a duke or marquise idk, and take in fl as his mistress. Ml had a reputation for having a lot of mistresses but they are women like fl who only came under ml for protection. Ml doesn't have any type of relationship with the mistresses other than friendship.
Like wind on a dry branch
