[JUL-169] If i didn't look into my father-in-law's bondage room, the couple's happiness would not have broken. Tsubasa Yano

It's been a few months since I got married and started living in my husband's parents' house. I was nervous at first, but... Thanks to my kind father-in-law, I feel like i'm used to living here. However, there is only one mysterious thing. My father-in-law's room at the back of the second floor had a strange atmosphere that i was just trying to get close to. One day, i came back home to finish the errand to go out until the evening earlier than planned, i heard a slight groan from my father-in-law's room in the back of the second floor.
