Silence is Key

Hana never was popular
Isamu was popular
Shizuki is... there
Hana was always the strange girl who never fit in, never spoke, and always wrote her life out. One day when Isamu and his sister, the most popular 1st years, are kept inside during lunch, they meet Hana, who was always there, but no one really paid her mind. Soon, Isamu begins to help Hana learn how to speak her thoughts, leading to a strong friendship between Hana and Shizuki and a sweet love story between Isamu and Hana.
