Kokoro ni Sotto Sasayaite

Suzuna is the basketball manager and an ordinary high school girl. But you wouldn’t guess at it because she’s short and has a cute baby face like an elementary student. Which doesn’t sound so bad until she hears that her crush, Yuuji-senpai, only looks at her as a little sister because of her cute appearance. How will she be able to make Yuuji-senpai look at her not as a sister? Source: MU Extra chapter from Mind Game volume 2.
