Roommates like to post all kinds of copywriting hinting at transfers in Moments. She just sent it and would remind the people in the dormitory to transfer money to her every time. I was wronged once and I don't want to be wronged a second time. Unexpectedly, she held a grudge and went to the school's universal wall to spread rumors that I was stingy. I took out several gigabytes of chat history backup. Did she think that if she disbanded the dormitory group, she wouldn't be able to see the chat history?
