Who Are The Main Characters In 'Promoting The Free Use Wife'?

The web novel 'Promoting the Free Use Wife' has this wild dynamic between its two leads that hooked me from the first chapter. The husband, Lin Yan, is this cold, calculating CEO type who initially sees marriage as purely transactional—until his wife, Su Xiaoyu, completely upends his worldview. She’s bubbly, stubborn, and secretly brilliant, using her 'free use' role to dismantle his emotional walls. What I love is how their power balance shifts: Lin Yan thinks he’s in control, but Su Xiaoyu’s emotional intelligence and quiet rebellions (like turning his corporate events into chaos with her 'accidental' antics) force him to confront his own vulnerabilities. The supporting cast adds spice too—Lin Yan’s scheming ex-fiancée, Su Xiaoyu’s protective best friend who distrusts the marriage, and the hilarious office employees who place bets on how long the couple will last. It’s a rollercoaster of misunderstandings-turned-genuine-feelings, and the way Su Xiaoyu’s backstory (her family’s debt forced her into the arrangement) gradually intertwines with Lin Yan’s growth makes their eventual love feel earned, not rushed.

What stands out is how the author plays with tropes—the 'contract marriage' setup feels fresh because Su Xiaoyu isn’t a passive victim. She weaponizes her perceived naivety, like when she 'innocently' leaks Lin Yan’s allergies to his rivals, sabotaging his business dinners. Their banter is gold, especially when Lin Yan starts reciprocating her mischief by pretending to be a jealous husband in public. The novel’s Chinese web fiction roots show in its exaggerated corporate drama (evil uncles! secret inheritances!), but the core relationship feels grounded. I binged it in three days, and that scene where Su Xiaoyu finally calls him out for treating her like a 'wife prop'? Chills.

Lin Yan and Su Xiaoyu totally own the story in 'Promoting the Free Use Wife,' but the side characters steal scenes too. There’s Lin Yan’s stoic assistant, Zhang Wei, who deadpans advice like 'Sir, pretending to hate your wife’s cooking won’t make her stop bringing you lunch,' and Su Xiaoyu’s former university rival, now a gossipy coworker determined to expose their fake marriage. Even Lin Yan’s grandmother, who orchestrated their union, has this mischievous streak—she fake-cries to guilt him into dates. The novel’s charm is how everyone, even minor players, feels like they have their own agendas weaving into the main couple’s chaos.
