[Transmigrate into a book + Substitute + Mute + Exclusive Devotion + Unhinged + Male Lead Turns into a Scheming Tease Later]
[Dark, unhinged male lead who fights to claim what's his VS clear-headed heroine who makes money and 'trains dogs']
After working overtime late into the night, Yu Ning dies suddenly and transmigrates into a novel as a cannon-fodder supporting female character. Because she looks like the novel's mute first love, the family sends her to the unhinged second male lead, Chu Wang, as a substitute.
She's not Chu Wang's only substitute. The obedient ones just get dumped. The disobedient ones are taken care of permanently.
To survive, she has no choice but to pretend to be mute and obedient, waiting for Chu Wang to get tired of her and dump her, while she collects a breakup fee on the way out.
But one substitute after another leaves.
She waits a month, two months, three months...
Chu Wang still doesn't dump her. Instead, someone pulls her into his arms and asks whether she loves him.
Wait, is that how this is supposed to go?
Shen Huan decides she's done serving him and brings in the first love.
A substitute could never compare to the real thing. She firmly believes that with He Yuru around, Chu Wang won't give her another thought.
She takes Chu Wang's money and goes out of town to start over.
To celebrate her freedom, she goes to a bar. A friend kindly orders a masked man to dance and liven things up.
Shen Huan gets drunk. She looks at the man with his awkward, uncoordinated movements and finds him more and more familiar.
After serving someone for so long, she wants to try being the one served for a change.
She lifts the man's chin. "Be good and say something sweet to make your big sister happy."
The man takes off his mask. "Sure, big sister."
Shen Huan is horrified. "Chu Wang."
Very good, I like it.
