Lu Yibei devotedly pursued his moonlight Zhou Zhou for two and a half years, only to be treated as a "simp." Disillusioned and having given up, he unexpectedly discovered that his "good brother" Ji Qingqian, whom he had known for years in a game, was actually a girl. Cold on the outside but warm on the inside, Ji Qingqian retook a year of high school for Lu Yibei to get into the same university, moving from online to offline to bravely chase love. With her company and encouragement, Lu Yibei gradually walked out of the haze and became mature and steadfast. Together, the two faced the entanglement of the former moonlight, the challenges of supporting characters, and family tests, ultimately reaping a love where they rushed towards each other mutually.
