The 24-year-old physics genius Qi Luo and his schoolmate, Chinese literature teacher Bai Yuan, are in a relationship. After a period of the silent treatment, he writes a pixel mini-game to vent his frustration, where the level difficulty is completely bound to their emotional state. It unexpectedly goes viral, turning three million players into "relationship hurdle hostages." The male protagonist expresses his clumsy affection in fancy ways using physics formulas, game code, and Hanfu pixel love letters, successively turning down million-dollar copyright buyouts from big corporations, while also dealing with colleague gossip, wall-to-wall public spectatorship, and a mother-in-law's home visit. Online players follow the drama and assist the whole way through, as hard-core rationality and soft affection collide in a sweet, fun, and healing story.
