Yuzuki-san Chi no Yonkyoudai. EP3 - Something's Bothering Gakuto

Mr. Kirishima has shown interest with the Yuzuki sons, and has tried to find ways to connect with them. One day, when Hayato is late to pick up Gakuto from the bus because he fell asleep, Mr. Kirishima sees Gakuto sitting along one the front steps. He invites Gakuto in and puts on a show to watch. Gakuto enjoys being at Mr. Kirishima's house, so when Hayato comes back he asks if he can come over another time. Hayato rejects the offer at first, but soon realizes he needs help watching over his brothers, and allows Mr. Kirishima to watch Gakuto after he comes home from school.
