At the start of the school year at Jiangcheng University, Lu Jingming, a seemingly lazy former professional gaming prodigy who actually earns a fortune each day by playing games for others, is forced by his aunt to move into a luxury villa with a roommate. He expects to enjoy a quiet life doing as little as possible, but his new housemate turns out to be Su Qinghan, the aloof campus beauty famous throughout the university. To make matters worse, Lu Jingming unexpectedly awakens a System that can read "emotional microexpressions," allowing him to see people's true feelings and inner thoughts. On the first day they live together, he sees the elegant, frosty beauty sitting at her computer, keeping up her cool, expressionless goddess image while furiously hammering away at her keyboard. Her gaming ID is none other than "Ice Without Ice," the sworn enemy he has been trading insults with for an entire year!
It turns out that this cool goddess is not only a terrible player who loves gaming, but also a hardcore gaming addict who loses her cool the moment someone flames her. To keep Su Qinghan from realizing that he is "Mingjing," the guy who has been crushing her in game every day and taunting her mercilessly, Lu Jingming begins the difficult daily task of pretending to be someone else in person. But as they spend more time living together, their secret identities teeter on the brink of exposure amid constant bickering and intense flirtation.
When Lu Jingming makes his triumphant return at the finals of the National College Esports League, and the campus beauty whom everyone sees as an ice queen starts wildly cheering him on from below the stage, the whole university is stunned. What no one knows is that the night before, this perfect couple was fighting tooth and nail over a red buff in game. When the ice queen melts and his online nemesis is unmasked, who will come out on top in this cohabitation saga full of public displays of affection and snarky banter?
