Shall We Kiss?

Emmanuel Mouret's romantic comedy Shall We Kiss? begins with two strangers who end up attracted to each other, even though they both are involved in relationships with others. The woman refuses to kiss the man goodnight after a dinner together, explaining that a single kiss can alter a life. This set-up acts as a framing device for the main story, a tale she shares with him about friends who complicate their lives by becoming sexually involved.
