Nagasumi is still trapped in the same ridiculous domestic sitcom, except now the OVA format lets the comedy breathe without padding. Each episode is a self-contained bit of controlled chaos: overprotective dads, actual animation that doesn't cut corners, new characters who slot perfectly into the existing madness. If you watched the TV series and thought "this works best when it stops overthinking itself," these shorts are exactly what you wanted.
Nagasumi is now in his third year of school, and life has not calmed down. San and Luna's fathers are as overprotective as ever, and Nagasumi has his hands full trying to keep the people around him in line while also coming to the aid of damsels in distress. The two OVA episodes are new standalone shorts that bring back characters from the TV series and add two new ones, all in a comedic romance.
