Kanon, a married woman who has been married to her husband for two years. She lives a happy life without any inconvenience except for one complaint. That dissatisfaction is my brother-in-law who lives in a two-family house. Kanon didn't really like her brother-in-law who didn't get a regular job and only came when she was hungry. However, there was a past that such a married woman could not tell her husband. When she was a student, she used to act as a dad on a whim. The past she wanted to erase for a married woman was found by her brother-in-law, who had a lot of free time on the net.
