ハニーレモンソーダ

Quiet, withdrawn Uka Ishimori has been nicknamed "Stone" since middle school for her blank expression. Entering Hachimitsu High School, she meets Kai Miura, a bright classmate with lemon-colored hair whose lightness reminds her of lemon soda. As Uka grows closer to Kai, his encouragement nudges her to speak up in class, make friends of her own, and slowly recognize what she feels for him.
