Gu Xiaoyu was woken up while sound asleep. She found her roommate Wang Tian'er sleepwalking again, muttering something about "big watermelons." Roommates Luo Meng and Su Jingjing were also woken up, but they were used to it and didn't take it seriously. However, the next night, Wang Tian'er, still sleepwalking, kept repeating, "Is the watermelon ripe yet?" Shockingly, she was saying this while pointing at her roommates' heads. Gu Xiaoyu, who'd been woken up, turned pale with fright. When Wang Tian'er walked up to Gu Xiaoyu, her face twisted into a ferocious grin. "It's ripe," she said, then immediately pulled out a knife. Gu Xiaoyu, terrified to the core, screamed loudly. The other roommates, roused from sleep, rushed to wake the sleepwalking Wang Tian'er. At this point, Gu Xiaoyu proposed moving to another dorm. The others thought instead that Wang Tian'er could temporarily move to the empty dormitory 205 upstairs. Little did they know, the next morning, a scream from Su Jingjing woke the rest.
