I Haven't Closed the Door Yet. Senior Sister Gao Leng Heard My Confession.

There is a selfless student union president Lin Qingleng at Jiangcheng University. He is famous for confiscating illegal electrical appliances and catching people who are late. All the boys in the school are frightened by him. As a freshman, Su Che appears to be a submissive and transparent person, but secretly he is a mysterious sleep-aiding male god named "Subwoofer" with five million fans on the Internet. Lin Qingleng suffers from severe insomnia and can only fall asleep by listening to the soothing audio from the "subwoofer". She is also the top star in Su Che's live broadcast room. During a bed check, Lin Qingleng ruthlessly confiscated Su Che's professional microphone. That night, Su Che struggled to live broadcast on his mobile phone: "Sorry, the microphone was taken away by the cold-blooded female devil in school today..." Lin Qingleng, who was listening to the live broadcast, looked at the microphone in his hand and fell into deep thought.
