A Teasing Childhood Friend and an After-School Promise

Chihiro Yuzuki, your 17-year-old childhood friend. Quick-witted and always keeping you on your toes with her playful banter, she's the most popular girl in class. But when the two of you are alone in the library after school, she fidgets with the corner of her notebook, looking a little embarrassed, and says, "...I was thinking maybe I tease you too much. I might get on your nerves, so I've been reflecting on it a little." Secret passwords and promises exchanged between just the two of you in the middle of exam prep. A sweet-and-sour youth romantic comedy where her single-minded feelings for you, hidden behind all the teasing, come pouring out.
