After My Three Roommates Died, Messages Kept Appearing in the Group Chat

I finished watching it at three in the morning and now I don't dare to go to the bathroom. The line "Don't look back" at the beginning immediately put me in a good mood. Originally I just wanted to read two chapters before going to sleep, but ended up reading it until dawn. During the whole process, I kept guessing who the murderer was, guessing the landlord, guessing the delivery person, guessing the roommate, but in the end I was told - the protagonist himself is also a dead person?? Goosebumps arose. The most amazing thing is the second-person part at the end, "Which floor do you live on?" I'm scared to look at my phone now. The author is very good at laying hooks. The mirrors, express delivery, and shutdown text messages in the front are all foreshadowing, and the second brush is all right. The size of the short story is just right, it doesn't drag out, and the twists come one after another. I recommend it to all friends who like rules and weird stories. Remember to read it during the day.
