幼い頃から影が薄く、周りの人に気づかれない生活を送っていた玻璃。大学生になっても変わらない───そう思っていたのに、気づいてくれる人が１人だけ現れた。それは同じ大学に通い、玻璃の隣の部屋に住む鯨井だ。実は、いつも玻璃のことを見てくれていた鯨井。初めてできた同年代の友達に玻璃の心は弾むけど、どうやら鯨井は“友達”以外の感情もあるようで…!? Ever since he was a child, Hari has kept a low profile and lived a life unnoticed by those around him. He thought nothing would change even after he became a university student, but then one person finally noticed him. That person was Kujirai, who attends the same university and lives in the room next to him. In fact, Kujirai has always been watching out for him. Hari's heart leaps with joy at having made his first friend of his same age, but it seems Kujirai has feelings for him that go beyond just being a friend...!?
