Misaki wakes up one morning to find her colleague, Soichi, naked and in bed with her! She remembers having sex with him but is too embarrassed to confess it. When she tries to play it cool, he tells her that he barely remembers it either, and that they should pretend it never happened. Misaki is a little disappointed after having heard his sweet words that night, but she tries to act normal. However, his attitude only makes her heart tighten up... What she thought was a one-night stand turns out to be a one-night target! A sweet nighttime love with a co-worker!
