It’s been several months since I got married and started living at my husband’s parents’ house. – I was nervous at first, but thanks to my gentle father-in-law, I now feel like I’m used to living at home. – However, there is one mysterious thing. – My father-in-law’s room at the back of the 2nd floor had a strange atmosphere as if I wasn’t approaching it. – One day, I returned home earlier than planned to go out until the evening, but I heard a faint moan from my father-in-law’s room on the second floor.
