Des:When I became university president, I was surprised by my son Les lack of ambition. Thinking that she might change after getting married, she forced Professor Oshimas niece Sora to act as a matchmaker, but... in fact, it was none other than Toru who was targeting her. He pretends to be a strict father who forbids them from having premarital sex until they are married. A year later, Tohru sends Manabu on a five-day business trip to implement his plan to train Sora.
