Yūtarō Terada

Yūtarō, nicknamed "Yū" and "Tera" by his peers, is one of Ren's friends at school and is both sagely and mature. Unlike Ga-chan, he tends to be more realistic and is reluctant over Ga-chan's matchmaking attempts because of Ren's increasing anxiety over Mayuka. In middle school, he attended the same cram school as Sayuri Uehara, and they began dating. However, they broke up abruptly when Sayuri assumed Yū was cheating on her. Yū regrets hurting Sayuri and realizes their relationship failed because of lack of communication and his immaturity, but knows they cannot return to the way they were. Instead, he encourages her to make peace with Daiki when troubles appear in their relationship(even though he is still in love with her), and tries to move on from her once she has done so.
