I've been dating Mari, who isn't beautiful but has a good personality, for three years, and I'm starting to think about getting married...One day, I decided to go on a hot spring trip with my girlfriend's parents, and when I met her mother, Naho, for the first time, I fell in love with her at first sight because she was my ideal type.However, Naho is her mother and her husband is also there, and they fall in love as soon as they meet.Shaken, I head to the hot spring alone and find Naho already taking a bath, but I end up touching her beautiful wet body even though I know it's wrong...
