my brother's wife's blown milk... all i know about her family is her husband.

Ruisan (Aiki) was able to marry my older brother, who was a male relative. She's a little too enthusiastic about her brother's energy, but she's also a bright and energetic person who kindly treats me and my father-in-law Yoshisuke. I am enthusiastic about keeping my brother's words on the business trip, and trembling the explosive milk of proud of taking care of his father-in-law who has hurt his hip. One day, I couldn't control my excitement because I was looking at Mr. Yui taking a shower and came up with an operation.
