Arigatou, Ayamachi.

He's a dad. Why would he do that? Daycare worker Yukari was too busy with the children for love. In fact, she didn't have any opportunities to meet people in the first place... But, just when she was thinking that, she found herself having drinks with her friend Manami's boss, Koji. The man Manami said was "good-looking, but strange," was a gentleman and escorted Yukari back home. However, having had a few too many drinks, the two of them fell on to the bed, and... wound up kissing. The following morning, Koji was gone. Yukari was in agony recalling the previous night!! With those memories in tow, she did her work, but the "handsome dad" there to pick up one of the children was... the same man she had just shared her bed with!?
