All the Boys Are Called Patrick (1959)

Blonde girl Veronik (Nicole Berger) dates her cousin Charlotte (Anne Collette) who lives in the same dorm and meets the talkative man Patrick (Jean-Claude Brialy) outdoors. Veronica was indifferent to Patrick's chat-up at first, but finally agreed to have tea and chat with him under his stubborn offensive. The two got along happily and made an appointment at 9 o'clock the next day. Patrick, who had just finished dealing with Veronica, ran into Charlotte and immediately followed him like a fishy fly. His clever words made the serious Charlotte smile and succeeded in getting a kiss from a young girl. The next day the two sisters went to the date at the same time, but were surprised to find that their perfect Patrick was the same person.
