Taichi wants to talk to Kohei, but Maya, who views Taichi as a rival, blocks every attempt.

Taichi still hasn’t told Kohei that he’s planning to leave the university. But Kohei senses that Taichi might be drifting further away…

As misunderstandings grow between Kohei and Taichi, Taichi visits Kohei’s home to confront the distance forming between them.

Taichi starts accompanying Kohei to class, taking notes in exchange for boxed lunches.

Since their kiss, Kohei and Taichi have become more conscious of each other… but things aren’t so simple.

Suddenly appearing in front of Taichi is Maya, a new student with hearing loss who seems close to Kohei. Taichi is troubled by their seemingly intimate relationship…

After discovering the meaning behind Kohei’s sign language message when they parted, Taichi spends the summer unable to express his own feelings. One day, the two meet again by chance at the summer festival…

As those around him begin thinking seriously about their future, Taichi feels lost. A chance meeting with Seishiro Sai shakes his destiny.

Kohei grows worried about the sleep-deprived Taichi, who’s started a part-time job at a sign language service company. But Taichi’s momentum won’t stop now that he’s found his passion.

During summer break, Kohei and Taichi go together to a summer festival—just the two of them!

As Kohei slowly begins to open up to his cheerful classmate Taichi, a hint of loneliness still lingers in his expression…

Kohei and Taichi connection deepens, sparked by something as simple as sharing a hamburger from a bento box.
