A middle school on an island. The boy Nishikata is often teased by Takagi, the girl sitting next to him. Although he tries to come up with various plans to retaliate against her, he is always seen through and fails. Laughing and joking, the two spent every day bored and irreplaceable for each other, but Takagi was about to move... Ten years later, Takagi (Mei Nagano) returns to the island as a trainee teacher! Nishikata (played by Fumiya Takahashi) is also struggling for life as a physical education teacher. When the two meet again, it seems that there are quietly ripples in their hearts, and the days when they stopped "teasing" seem to have begun to move again. Their memories were still there, the sparkling waves on the sea were still there, and the beautiful scenery on the mountains was still waiting for them.
