[Modern romance] [Love at first sight] [Devoted puppy] [Wife-doting fanatic]
After witnessing all the messy drama in her best friend's older-woman-younger-man relationship, along with her younger boyfriend's endless attention-seeking antics, Xie Zhaoyan swears she'll never date a younger man.
Lu Wenzhao, who is seven years younger than Xie Zhaoyan and studying abroad, returns to their alma mater for an event and falls in love with her at first sight. He plans to confess, but accidentally overhears the woman of his dreams say she won't consider anyone younger than her.
With no other choice, the male lead finds a cousin who looks most like him and is three years older than the female lead. He impersonates his cousin, putting on the act of a mature, proper CEO, and the two begin dating under the pretext of a matchmaking setup.
They date long-distance for two years. After Lu Wenzhao returns to China, he plans to live with her for six months, with marriage in mind.
Xie Zhaoyan goes on a business trip and makes a last-minute detour to a business dinner in Country A, where she meets the real cousin. She realizes she has been deceived.
On their first night back in China, she confronts her boyfriend: "Who are you, really?!" When she learns he's seven years younger than she is, it's like a bolt from the blue! She completely loses it!
Lu Wenzhao clings to her leg, sobbing and swearing that he'd rather die than let go. His crybaby side is exposed, too.
Xie Zhaoyan: ...So the CEO act was fake, fine, but how did I end up with a whiny baby?
