It's been two weeks since my wife got pregnant and went home. Meanwhile, Tatsuya was enjoying living alone. However, the lonely life without a conversation partner began to cast a shadow on Tatsuya's heart little by little. At that time, my sister-in-law's sister Hanane (Kanon Kanade) came to see the situation. Tatsuya is surprised and pleased with the sudden visit. Hanane is welcomed with a big welcome, but the real purpose of Hanane's appearance was to eliminate daily frustration with Tatsuya.
