Yagami-kun's household is a mess of tangled romantic complications. His mother looks like a 14-year-old, and he makes no secret of being in love with her. His teacher is also smitten with her, so the two rivals clash in the classroom while scheming together against their shared enemy: Yagami-kun's father. The father's secretary loves him, but after learning how young his wife looks, she turns her interest to the son. Yagami-kun is left torn between his own mother and a naive girlfriend who rides a motorbike. Then a new student joins the class, a perfect lookalike of his mother whom everyone falls for. There's one catch: he's male. The result is a three-episode comedy OVA built on absurd romantic situations.
