Rihito Sawaguchi

Rihito Sawaguchi (沢口 理人 Sawaguchi Rihito) is the childhood friend of Shinya Momotsuki, Yuzuki Shimada and Shōta Shizuka.

He is the very cool and casual type who is Yuzuki's secret crush that his feelings toward her are not entirely clear at first, but it is eventually revealed that he's in love with her. However, he rejects her on account of Shouta's feelings, as well as the fact that her feelings toward Shouta are so very strong and her "dependence" on him so strong that there would be "no meaning" to her loving him. Despite this, he has expressed hope that someday he'd be able to make her look more completely his way.
