Happy Lesson: Advance (2003)

Chitose, a high school student, shares his house with five women he calls his mothers, who also happen to be his school teachers. One might think the continued attention of this many "females" would be a good thing, but too much attention can prove to be painful. Not only is he the subject of their smothering abuse at home, but at school as well. Even when things finally calm down at night, all the rooms in the large house are occupied by his "moms", so Chitose must sleep on the living room couch.
