VENX-059 Suddenly, my wife's sister barged in and kept me on edge for a whole night and day

Tatsuya's wife left him after a huge marital quarrel. He tries to make up, but it doesn't work out. At that time, his sister-in-law Kana was worried and offered to mediate the fight. Tatsuya, who has no choice but to thank her for her help, raises Kana to her house to get her advice... but she can't hide her upset when Kana closes in on her defenselessness. He tries to run away and takes a bath, but she says Kana should join him.
