Psychiatrist Satoko and her friends Nao and Mizue are on the wrong side of 35, sliding quickly towards 40. Satoko and Nao are both adamantly single, but start realizing that something might just be missing from their lives, with Mizue on the flipside as a bored stay-at-home mom. A chance meeting throws Keitaro into Satoko's path after he gets hired as a clinical psychologist at the hospital where she works and ends up paired with her. Sparks and tempers fly as they clash, but there is the possibility of a future. (Source: SakuraPrincess)
