{Aoi x Inosuke | AoIno} The Letter

A mysterious letter showed up in Inosuke's locker. A letter that seemed so formal with such a unique handwriting. Inosuke, being dull about such a letter, showed it to his friends. The letter was so anonymous- none of them could think they would find the person who wrote the letter. However... that specific handwriting began to pop up everywhere- and the person who wrote that letter would be exposed.
