Hikaru, the wife who decided to go to her sister's visit and her husband's business trip. Her brother-in-law kindly allowed me to use her spare room until her sister left the hospital. A brother-in-law who has grown up with a naive and grown-up Hikaru for the first time in a long time. Without knowing her brother-in-law's thoughts, she is forced to take care of her brother-in-law. Hikaru, who has a strong refusal personality, can not refuse his brother-in-law's onslaught, and if he notices it, he will deepen the relationship and feel like squirting.
