This is a two-faced, doting love story between a friendly part-timer at a cafe and a ditzy, awkward college student!

Shuu, a college student who works at a bookstore in a mall, actively hit on Chihiro, a part-timer at the cafe, and they end up in a relationship. Shuu is awkward and not not good at handling customers, so Chihiro, who is friendly and always smiling, allows Shuu to relax. Finally, it's time for their first sleepover date. Chihiro's sharp expression in bed makes him seem like an entirely different person and tugs at Shuu's heartstrings. The next morning, Chihiro is acting as he always does, making Shuu wonder if he was just imagining things. However, now he's feeling more and more uneasy around Chihiro as a result!
