Iroha Natsume and her husband work at the same company; they met there, fell in love, and got married. Within the company, there is a colleague who really likes Iroha Natsume, but due to his shyness in confessing his feelings, he missed his chance and deeply regrets it. One day, at a company party, Iroha's husband got drunk and lost his way home, and so this colleague took him to his house. There, he ran into Iroha again; she was still as beautiful and sweet as before, making it impossible for him to control his emotions in his drunken state.
