My Roommate's Weird Sister Wants to Teach Us the Rules.

The company arranged accommodation for her as a fresh graduate. On the first day she moved in, her roommate brought her sister with her. The eldest sister who was twenty years older than her, with a face full of vicissitudes, pointed at me and said to the other roommates: "You young people like to order takeout, eat junk food, and spend money lavishly!" "I help you cook, and you can just give me two thousand yuan a month!" "Besides, I have neurasthenia, so don't come back so late and affect my sleep!" "Also, the room with the balcony looks good to me, please leave it to me!" I was confused, who was letting out this bitch?
