VENU-927 Suddenly, my wife's sister barged in and kept me on edge for a whole night and day. Kanon Soun

It's already been two weeks since my wife got pregnant and went home. Meanwhile, Tatsuya enjoys living alone. However, the lonely life with no one to talk to is beginning to cast a shadow over Tatsuya's mind. At that time, her daughter-in-law's older sister Kanon came to see how she was doing. Tatsuya is surprised at her sudden visit, but she is delighted. She is warmly welcomed and she welcomes Kanon, but her true purpose when Kanon appeared was to relieve her daily frustration with Tatsuya.
