One day, Yuki, a university student, is in trouble when she is rescued by Itsuomi, a senior student at the same university. Even though Yuki is deaf due to a hearing impairment, Itsuomi is unfazed and treats her naturally. Yuki gradually becomes aware of Itsuomi, who makes her feel a new world...

Yuki is a typical college student, whose world revolves around her friends, social media, and the latest sales. But when a chance encounter on a train leads to her meeting friend-of-a-friend and fellow student Itsuomi-san, her world starts to widen. But even though Itsuomi-kun can speak three languages, sign language isn't one of them. Can the two learn to communicate the budding feelings between them?
