Nobunaga is a middle school teacher who has long dreamed that his life will turn into a dating sim, with a girl who adores him suddenly appearing out of nowhere. That wish comes true in an unexpected way when Kicho, a fourteen-year-old girl, shows up in front of him announcing that she is his wife. She seems to have come from Japan's Warring States period, and she believes he is the famous Oda Nobunaga. She wants to have his children. What follows is a short-format age-gap romantic comedy with ecchi and supernatural touches, pairing a teacher whose head is full of gal game logic with a princess whose thinking belongs to the Sengoku era.
