Suzu Sakuma

佐久間 すず

"Satoshi's younger cousin who is also a well-known teen model. Suzu fell in love with Yuu immediately when she saw his picture, which motivated her to do the cosmetics commercial that she was shooting when she found out that he would be in it. Yuu also became Suzu's math tutor through Satoshi's efforts. Suzu tried to express her feelings for Yuu, but he was not interested in her and only saw her as a kid sister. She also tries to tear Yuu and Miki apart after mistakenly believing that Miki is a cheater, but fails. She develops a love/hate relationship with Kei." (Source: Wikipedia)
