After a while, the discussion between two girls caught my attention, because as far as I knew, they shared a dorm room with Ke Xin.
"Ugh, last night was so annoying. I have no idea who it was being so dumb, constantly knocking on our dorm door. When we opened it, there was nobody there, but as soon as the door shut, the knocking started again. It went on all night, and I couldn't get any sleep."
"That's true. I must have opened the door at least twenty times last night. If Ke Xin hadn't taken over later, I think I would have gone mad."
"I went to report the situation to the dorm manager this morning, and she said I was lying. She didn't sleep all night and claimed she didn't hear any knocking."
"If someone knocks again tonight, I'll bring her over to see whether I'm lying."
"Let's not bother. I bet no one will knock tonight. Who has nothing better to do than to knock on doors every night? Do you think someone is seeking revenge on us?"
