Nakatani (Dean Fujioka), who is eager to get Karen (Igarashi Mio) to take up extracurricular activities, invites Shiho (Tabe) and Ichigo (Nagai Kana) to a trial English class. Although Shiho is reluctant, saying “It’s too early, he can’t even speak Japanese yet,” Nakatani explains that “experience is a weapon that parents pass on to their children,” and explains why children should try as many things as possible from an early age. One day, Reiko ( Noriko Eguchi) invites the Nagano and Murakami families to go glamping. Nakatani and Karen, who are in Japan with their wife Juri (Shimabukuro Hiroko), also join, and the three families all get together!
