13 years ago, Tatsuomi died in an accident and is then reincarnated as middle school student, Fushimi Arata.
And then one day, a new teacher comes who was his previous life's lover, Midorikawa Utako.

A reincarnation heartful story.

The office stories of a kind hearted, weak willed, witch senpai and her relatable, simple but nice kouhai that started over a cup of magically warmed coffee.
