The only daughter, Nozomi, has fulfilled her dream since she was little and passed the dancer audition for a famous theme park. At the invitation of her husband, Takahiro, she will go on a hot spring trip to celebrate with her Sayuri couple. Then came the hot spring inn. It's been a long time since she's gone on a family trip, so Sayuri stretches her wings and soaks in the bath, drinking too much alcohol that she's not used to drinking. How long has it been since then? Nozomi and her husband are not in the room, and Takahiro is alone with Sayuri.
