I, Zheng Jiahao, am a freshman at Dongshan University. On the first day of school, I met the innocent Bai Yueguang Yang Xinru. I was about to start an innocent campus romance, but accidentally I ended up sharing a room with a sister Li Danyin who was a few years older than me. What's even more outrageous is that my senior sister dragged me to accompany her at night because she was afraid of ghosts, and my tutor sent me an 'academic seminar' message in the middle of the night... Wait, sisters, I'm just a male college student, not a time management master!
