From Now On, I’m Going to Steal You Away!!! – Temptation ♥ Rivalry ♥ Sisters

Ishidou Narumi, a student attending a rural all-boys' school, spends his noisy but enjoyable days with his slightly ditzy best friends. He has a "secret" that he has not made public. In this all-male school is a popular, gentle health teacher named Mitama, who seems to be the human embodiment of healing. Another one is Aya, his homeroom and chemistry teacher, who is feared because of her sharp eyes and strict attitude, but is also popular because of her model-like appearance.
