Lin Mo, a master of computer science, is trapped in his heart by his girlfriend Su Ran's "betrayal" and dropping out of school a year ago. One rainy night, a garbled post on the campus anonymous forum "Confessional Room" that was deleted instantly dragged him into the quagmire. In order to find the truth, he and Xia Wanxing, a campus reporter who is dedicated to justice, were forced to join forces and face the "disqualification game" controlled by the Jiangcheng University Student Union. When the truth of betrayal is revealed layer by layer, in the whirlpool of power and emotion, can the evening star that once illuminated the ivory tower be his salvation? Under the mist, a belated confession is about love, but also about truth and justice.
