I felt strange on the first day of college when I opened the door to my dormitory and found some absurd words on the wall.

The WeChat group for new students was flooded with messages. When I opened it, I happened to see a graduating senior sister post a sentence:

"The girls' dormitory building 18, room 309, is a good dormitory. After all, among the humanities students who were recommended for graduate school at Tsinghua University, there were only three, and they were all from that dormitory."

I stepped out of the dormitory door and looked. Well, "18-309" was clearly written on the door. It's no wonder I managed to grab this dormitory!

The dormitory had bunk beds with desks underneath. Starting from the right side near the door, the bed positions were labeled 1 to 4. I chose the second bed.

While I was packing my things, two more roommates arrived. My phone buzzed, and I checked it. It was a message from one of the girls who hadn't arrived at the dormitory yet:

"Hey, sisters, something came up at my house temporarily. I estimate it will take a few days before I can come."

The dormitory was formed by students from the same major during the summer vacation. During the four-person conversation over the break, things were pleasant. The girl who had something come up was named Qiao Qiao. We only knew her name, and she was quite mysterious. She rarely spoke in the group chat and wasn't particularly close to us. The remaining three of us were from City A. Although the three of us didn't meet up during the summer vacation, we created a small private group because we all loved playing games.

On the first day of school, we exchanged a few words in the group chat just to show our presence. Suddenly, Qiao Qiao said:

"Sisters, remember to abide by the rules of dormitory 309, okay~"

After saying that, she didn't speak in the group chat anymore.

I looked, and everyone "coincidentally" avoided mentioning the fourth bed. Chen Luo Luo chose the first bed. She was a girl with short hair and glasses, giving off a well-behaved impression. Zhang Wen chose the third bed. She had a high ponytail and wore work pants. She was a cool girl.

After packing things all day, I was already tired. Chen Luo Luo went to take a shower first. After a few minutes, she came out of the bathroom wrapped in a towel and asked:

"Hey, did any of you take my shower gel? I left it in the bathroom in the afternoon. It's the Zhumalong brand!"

I was about to respond when, for some reason, I suddenly remembered the words on the dormitory wall-

"If the shower gel in the bathroom disappears, don't make a fuss about it."

While I was lost in thought, Zhang Wen spoke up:

"I don't know. Maybe you forgot to bring it in?"

I don't know why, but after Zhang Wen finished speaking, I suddenly felt a chill all over my body. The lights in the dormitory went out abruptly, and then they came back on almost immediately. As the lights turned on, I heard someone ask:

"Did you take the shower gel?"

At this moment, Chen Luo Luo was in the bathroom, and Zhang Wen was sitting behind me, but that voice clearly didn't come from behind me.

That voice came from the entrance, from the fourth bed.
