French movie about family in Paris

A movie about a family with (i think) 3 daughters. the main character is one of the daughters, and to be honest i don’t really remember what happens next. i know one scene where the parents invite a guy, for the oldest daughter, over for dinner, and they start kissing in the kitchen. it was on Netflix and i remember the cover being the yougest sister with a towel wrapped around her hair and a facemask on.
