Taichi, a cheerful and outgoing college student, meets Kohei, a reserved and partially deaf young man, in the first installment. Their bond deepens as Taichi becomes Kohei's notetaker, and they navigate the challenges of communication and emotional intimacy. In "Limit," the story shifts focus to the complexities of their relationship as they transition into adulthood.

The manga examines themes of self-worth, dependency, and the nuances of love between two individuals with differing needs and perspectives.

Secondary characters, such as Ryu and Maho, provide additional layers to the story.
