Yuuyuu Jiteki.

Chihiro Suzuki, a serious and reserved college boy, meets Miyu Washio, an older girl with an incredibly positive attitude, while working at a convenience store near his new home. “Let’s make some happy memories right now!” Her unpredictable ideas for “fun” — and her wholehearted enjoyment of the moment — gradually transforms his dull and uneventful daily life. From their slightly offbeat conversations, an unexpected new chapter in their lives begins. This is a sweet and fresh coming-of-age romantic comedy that starts with “friendship”!
