Hijiri Koganei[]
Tsuchiya offers romantic advice to Hijiri, and at times appears as a joke romance candidate, considered equally handsome to the candidates.
Unfortunately, because of the amount of girls who have flung themselves in front of his car to get to Hijiri, he is on a watch list.
Anzu Hoshino[]
Tsuchiya genuinely appreciates Anzu's presence in Hijiri Koganei's life, and considers her to be a very good influence on him.
