Tonikawa: Over The Moon For You

Nasa overexerts himself doing work and catches a cold. Despite insisting that he is fine, Tsukasa tells him to rest as an obligation for being his wife. Sometime later, Tsukasa and Nasa put on yukatas and attend the summer festival. There, they eat takoyaki, then meet Aya and Chitose at the goldfish scooping game, and then pray at the shrine. The night concludes with Tsukasa and Nasa watching the fireworks show with Kaname, Aya, Chitose, and her maids. (Source: Wikipedia)
