S1, E4: Fujiko's brother Toshimune, who studies at her apartment, ends up being tutored by Nishina. As thanks, Fujiko promises to cook for him. Though Toshimune grows attached to Nishina, he becomes suspicious of his apartment, which stays dark even during the day. Convinced someone suspicious should not live next to his sister, Toshimune barges into Nishina's room. ©Ro Shimafuku, Natsuko Umezawa ©NTV
