Stagione 1 di Boin in anteprima dal 25 agosto, 2005.

Daisuke is a new teacher in school. He became popular with everyone in a matter of days. He conducts a class that allows his students to role-play as whatever they wish to be when they graduate, but some say this is a plot to spend extra time with the girls, and the girls expect more then just lessons.

On spring break, Daisuke is excited for his vacation on a tropical island for some well deserved relaxation and girl watching. He finds himself quite inexplicably popular with the ladies as well. Nao and Mitsugu follow him there as well competing, as usual, for his attentions. Meanwhile he meets his cousin Maya again after a long time as well as the wild Kanae and her friend Mika.
