Yuutarou Terada

Ytar nicknamed quotYquot and quotTeraquot by his peers is one of Ren039s friends at school and is both sagely and mature. Unlike Gachan he tends to be more realistic and is often holding back Gachan039s matchmaking attempts so as not to trouble Ren. In middle school he attended the same cram school as Sayuri Uehara and they began dating. However they broke up abruptly when Sayuri believed Y was cheating on her. Y regrets hurting Sayuri and realizes their relationship failed because of lack of communication 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 and moves on from her once she has done so. Source: Wikipedia
