Yuka Matsuyama

Mariko Nakasu
Shuuji and Mariko grew up together as childhood friends, since he was Mariko's neighbor and sempai from tennis club. He liked Mariko since they were little too, but couldn't tell her because she, running away from being hurt by her own feelings, moved to study in Tokyo.
