Kanokon - Season 1 Episode 6 Can I Please Do It?

Japanese New Year has come, and while Kouta at first is enjoying a quiet stay at home alone, Chizuru soon comes and tries to heat things up by distracting him while he is writing, or taking off her kimono to reveal a school swimsuit. They eventually play a love dice game where the players get to do perverted things to each other. Nozomu shows up at the end and gets in Chizuru's way, and Kouta suggests they go to take part in hatsumōde. At the shrine, they meet up with Chizuru's brother and other friends from school. At the end of the day at the shrine, they all go back to Kouta's house.
