The story begins in 2003, during the height of a influenza epidemic. Zheng Xiao Xiang gets trapped in a broken elevator with a mysterious man. He calms her nervousness, and ultimately helps her out of the elevator. Since they are both wearing masks, and did not exchange names, neither knows who the other one is. In the confusion after being rescue, Xiao Xiang faints, causing a bystander to rip off his mask and peform rescue breathing. Next thing you know, she is quarantined in the local hospital after contracting the CIV virus from her would-be rescuer.
An intrepid reporter, Ren Jia Kai, has entered the quarantined area with the task of documenting the human cost of the epidemic. He meets up with Xiao Xiang and recognizes her from the elevator. He is, of course, the guy from the elevator, but, fully gowned and masked, she doesn't recognize him.
They fail to follow up on the sparks in elevator and go their separate ways.
Eight years later, she is a single mom. Her long-term boyfriend Ke Jie, who was the one who infected her with the CIV virus, has broken up with her and moved out. Jia Kai has become the CEO of a high-end public relations firm. Through a series of fateful mishaps and events, they meet up again. Can lightning strike twice?
The series contains the following examples:
- Age-Appropriate Angst: How Duo Duo reacts to Ke Jie leaving
- Break Her Heart to Save Him: Ke Jie
- Contrived Coincidence: While in the office, Xiao Xiang overhears two interns making fun of her. Of course, the boss/love interest hears too, and fires them on the spot.
- First Girl Wins: Jia Kai is taken with Xiao Xiang almost instantly; they don't hook up until years later, though.
- In-Series Nickname/Who Names Their Kid "Dude"?: Xiao Xiang and Ke Jie's daughter, Duo Duo. ("Duo" means "many;" "duo duo" means "a lot of.")
- My Beloved Smother: Xiao Xiang's mom tries to coerce Ke Jie into marrying her daughter, then, when that didn't pan out, showed up at Jia Kai's office with a fruit basket and some histrionics to get him to give her a job. When he publicly confesses to Xiao Xiang, she throws an engagement party even though they aren't engaged, and tries to push them both into marriage as soon as possible.
- The Mistress/New Old Flame: Ming Xin, to Ke Jie
- Shout-Out: The PR firm wants to use top model Tang Ai Wei. The name refers to a character Drunken to Love You where the model gave up on love to pursue her career. The two series share scriptwriters.

- Two Guys and a Girl: Jia Kai/Kelly/Ou Wei. Jia Kai and Kelly end up marrying each other, but after their divorce, Ou Wei attempts to pursue Kelly again.
- White-Collar Crime: Two interns were spying in Jia Kai's firm to steal proposals for another PR firm.
