『Yuu Sonoda』

Haruka's best friend since junior high school. She is the childish one out of the two. She often acts more conservative than Haruka, but occasionally gives in to Haruka's requests. Yū initiates that she and Haruka do something special together, in order to comfort Haruka's growing insecurity about their friendship. But what began as a way to comfort a saddened friend soon turned into something much more for the both of them. Yū's favorite food is everything that tastes like green tea mochi(bread, pudding, ice cream, sweets, etc.). She also shares romantic feelings for Haruka. Whenever Haruka tries to make Yū kiss her, Yū will often act embarrassed, but occasionally she will give Haruka surprise kisses. Yū and Haruka become an official couple at the end of the manga.
