Teasing Master Takagi-san - S01

Mano and Nakai are heading to the water park with their classmates Nishikata and Takagi. Before they can pick their first activity, Nakai suddenly dashes off with Nishikata, leaving his disappointed girlfriend behind with Takagi. Mano confides that Nakai had promised to ride the water slide with her-a ride said to make couples who go down together fall in love. Of course, Takagi sees an opportunity and comes up with a plan to reunite the pair while also finding a way to tease Nishikata in the process.
