Kimi ni Furu Kotonoha wa

One day, Komatsu Hinata, a high school boy who loves books, meets a blond-haired delinquent on the commuter train. Hinata was delighted that the delinquent seemed to show interest in his beloved novel. However, the delinquent ended up saying something unexpected, and harsh words were exchanged. Just when Hinata thought they would never meet again, he discovered the delinquent was Yukito Igarashi, a classmate who had not come to school since classes started.

A clumsy and bittersweet young romance unfolds between two boys who know nothing about love.
