A few months have passed since we got married and started living at my husband's parents' house. - I was nervous at first, but thanks to my kind father-in-law, I feel like I'm at home now. - However, there is one strange thing. - My father-in-law's room at the back of the second floor had a strange atmosphere, as if to tell me not to approach it. - One day, I finished my errands earlier than planned and came home earlier than planned, when I heard a faint groan coming from my father-in-law's room on the second floor.
