Synopsis

Morimura Shoko (played by Yukihira Aika) is a 36-year-old twice-divorced single mother who works as a temp employee while raising her daughter. At a high school reunion, she reunites with Kitada Kazuki (Aoyagi Sho), her first love who is now an OB-GYN, and is invited back to his hotel room. After years without intimacy, Shoko finds herself wanting to deepen their relationship — but Kazuki has no such intentions, and instead proposes that they become friends with benefits. Caught off guard by the blunt suggestion, Shoko struggles to accept such an arrangement.

Around the same time, she discovers that her classmate Shindo Hanae (Katayama Moemi) is already in exactly that kind of relationship with Kazuki. On top of that, her workplace superior Kuriyama (Niiro Shinya) begins making advances toward her.

Meanwhile, there is a reason Kazuki now seeks only no-strings-attached relationships — a secret from his past that he has never told anyone…
