[Villainess playgirl + sweet-on-the-outside, dark-on-the-inside puppy] Older woman-younger man pairing
[Both virgins]+ [Reunion after years apart]+ [Getting back together]+ [Secret identities revealed]+ [Younger man]+ [Puppy substitute]+ [Villainess]+ [Happy ending]
Mo Wanqing (female lead) has no choice but to return to China for an arranged marriage. Her fiancé turns out to be Gu Zhiyan (second male lead), the older brother of her “one true love,” Gu Zhizhou (third male lead).
Her “one true love” becomes her brother-in-law, the older brother has coveted his younger brother's girlfriend for years, and a copycat green tea girl gets pregnant to provoke her. But none of that is the most melodramatic part.
The biggest crisis now is that the substitute puppy she abandoned abroad three years ago, once a poor college student and part-time male model, has transformed into the “Young Master Li” (male lead), feared by everyone in Jiangcheng.
Li Sen has returned to China. The last three years have been worse than death, and he swears Mo Wanqing will pay him back for every bit of that pain, twice over.
He makes a dramatic appearance at her wedding and whispers in her ear:
“I spent three years tweaking myself to look like him. Are you satisfied, big sis?”
Gu Zhizhou (third male lead): You're marrying my brother? Then what am I?
Gu Zhiyan (second male lead): Delete them all. I'll pretend nothing happened, and you can still be my wife.
Li Sen (male lead): Did he give you a hard time, big sis? I don't need a title…
In public, Li Sen is cold and distant. In private, he buries his face in Mo Wanqing's neck and calls her “Master.”
Mo Wanqing fell for Li Sen long ago, but she mistakenly believes he sees her only as his “sugar mommy.”
So he hates her for playing with him and then tossing him aside like garbage.
She puts on a tough front, afraid she'll fall too deep again and love someone she shouldn't.
“Big sis, let's make up.”
