The Deadly Winter Rewind

In the previous life, when there was a cold wave warning of minus 30 degrees Celsius, roommate Zhou Qi insisted on opening the windows for ventilation. Even though Li Xin repeatedly told people that leaving the windows open in the northern winter would freeze people to death, she was still ignored. And was ridiculed by the remarks that "the young lady is just pretentious". After waking up from the cold several times in the middle of the night, Li Xin bought a combination lock and locked the window. Unexpectedly, Zhou Qi climbed up to the rooftop and cried to the whole school about being bullied by Li Xin's power. The other two roommates even used their silence to confirm Li Xin's crime. In the end, Li Xin was punished by the school and committed suicide by jumping off the building after being labeled as a "bullying". Opening his eyes again, Li Xin returned to the day when the cold wave came.
