I love how wholesome Kamiyama is. I was shocked he ruined that domino record but now that we know he can get stuck in a one way path to an outcome I can kinda see it now. Still, the fact he brought pudding as a snack and wore a party hat and sung songs for their trip was great. The beauty he sees in their trip is heartwarming! He was so into it he sat on Yutaka's lap on accident!
