History

Wang Dachui entered Jiang University as one of the four members of Dorm 515 alongside Luo Ye, Li Haoyang, and Shen Qiao. From the beginning, he was outspoken about his interest in campus beauties and gossip, but his enthusiasm for anime was genuine rather than merely an excuse to meet girls. During club recruitment, he joined the Anime Club after approaching an Asuna cosplayer and immediately outdanced the club members despite not wearing a costume. 3 20

Within Dorm 515, Wang became a source of constant commotion. His crude jokes, dramatic reactions, and habit of provoking Shen Qiao repeatedly led to playful fights, but he was also fiercely loyal to his roommates. When Shen Qiao's difficulties became known, Wang and Li Haoyang had already donated to help him; Wang's requested “reward” was to see Shen Qiao cross-dress. 43 94

He initially pursued the mysterious “Fish Roe Sauce,” openly declaring that his heart belonged to her and joking that he would acknowledge Luo Ye as his father if Luo helped arrange a meeting. His first meeting with Fish Roe Sauce was awkward, including an attempt to make conversation by discussing the age of a tree. 358 360 He later recognized that Fish Roe Sauce was Yu Qiuyu, confessed during a mountain climb, and agreed to take their relationship slowly. Yu eventually accepted a relationship with him. 398 408 411

Yu Qiuyu became a major motivation for Wang's self-improvement. Under her supervision, he ran five laps during P.E. despite collapsing afterward; the experience also led to their first hand-holding. He later maintained a running routine and, after reflecting on his wasted time and lack of direction, forced himself to finish a 3000-meter race with encouragement from Yu, Luo Ye, Li Haoyang, and others. 421 507 678

Wang nevertheless struggled with university responsibilities. He repeatedly overslept and skipped classes, drawing Yu Qiuyu's anger over his lack of ambition and future planning. He sought advice from his roommates, began making an effort to change, and briefly attempted to write a traditional-fantasy web novel. 661 662 673 1069

Near the end of his student life, Wang enlisted in the military. He concealed much of his anxiety behind deliberate silliness, intending to tell Yu Qiuyu before leaving for what could be two years away. 1230 After completing his service, he returned through Jiangcheng in uniform and reunited with Yu Qiuyu and the former Dorm 515 members, who welcomed him with a banner reading “Welcome back, King of Soldiers.” 1411

After discharge, Wang and Yu Qiuyu moved to Shancheng. He encountered exploitative job offers and contract traps while looking for work, which made him understand the hardships Yu had faced while living there alone. When a supervisor refused him leave to attend the birth of Luo Ye's child, Wang resigned; Yu then arranged for him to join her company, where he worked to avoid embarrassing her. 1413 1414

Appearance

Wang's appearance changes noticeably over time. During university, he is described as having a normal build before military service and later begins wearing glasses for myopia, which makes him appear more refined and scholarly. 719 1411 When discharged, he is slightly tanned, wears a military uniform with a red flower pinned to his chest, and claims that his post-service weight is muscle. 1411

• Wears glasses to correct myopia; Luo Ye describes the result as a “refined scoundrel” look. 719
• Favors conspicuous cosplay outfits, including Zenitsu Agatsuma's yellow wig and prop knife at a comic convention. 165
• Returned from military service with a somewhat more muscular appearance, though Li Haoyang disputes how much of it is muscle. 1411

Personality

Wang Dachui is uninhibited, dramatic, and shamelessly enthusiastic. He enjoys teasing his friends, spreading gossip, acting out exaggerated fantasies, and turning ordinary dormitory life into a spectacle. He often makes suggestive jokes at Shen Qiao's expense and reacts badly when others record his embarrassing behavior. 43 362 408

Despite his immature and impulsive habits, Wang is socially magnetic. His presence keeps Dorm 515 lively, and people across his clubs, classes, and sports circles encourage him during difficult moments. He is described as the dormitory's most popular member and its source of laughter. 678 1411

He is easily provoked by challenges to his masculinity or ability; telling him that he cannot do something reliably pushes him to attempt it. This trait causes trouble, but it also helps him persevere through physical training and long-distance races. 421 1026 His relationship with Yu Qiuyu gradually makes him more reflective about responsibility, work, and building a future together. 630 661 1414
