She was my classmate during our student days, "Ayumi Misumi." By chance, she transferred to work at my office, allowing us to reunite. And I had caught sight of her "secret" several times already. The first time was back when we were both in the same class... That memory still lingers vividly in my mind...

彼女は学生時代の同級生「美澄玲衣」。偶然、僕の職場に転勤してきて再会することになった。そして僕は、彼女の「秘密」を何度か目撃してしまっている。最初に「それ」を見たのは彼女と同じクラスだった頃。あの時のことは今でもはっきりと覚えている…。
