Seventeen-year-old Bai Yuexing accidentally transmigrates into a bracelet and returns to twenty years in the past, where he meets his mother, Bai Xianyu, still in college.
She is young and beautiful, lively and cheerful, and widely known as the campus belle of C University.
And the man holding his mother's hand is none other than...
His scumbag father, Gu Linfeng, who treated her as a stand-in for his beloved and eventually abandoned her.
Thinking of how his father would later go abroad with his beloved to live it up, leaving his mother to raise him alone through endless hardships, Bai Yuexing rubs his hands together. He has to get his mother away from his scumbag father as soon as possible and save her from a miserable life ahead.
But... why is his mom so obsessed with romance!!!
Bai Xianyu, the campus belle of C University, is strikingly beautiful, but soft-tempered, unambitious, and best at giving up. She never makes things hard for herself and is a bona fide couch potato.
The one thing she has stuck with for a long time, without giving up, is her love for Gu Linfeng.
Luckily, her dream comes true.
Except for a System that claims to be from the future and keeps pouring cold water on her, telling her to hurry up and break up with him.
Gu Linfeng is a famous figure at C University, handsome and adored by everyone. He was the one who asked her out, too.
The System says he sees you as a stand-in for his beloved.
Gu Linfeng is attentive and considerate. He'll casually buy her grape-flavored fruit tea, and countless little gifts to cheer her up.
The System says those are things his beloved likes.
Then comes an important anniversary. Bai Xianyu has spent ages preparing for it, eagerly waiting for Gu Linfeng to arrive.
But one phone call is all it takes for Gu Linfeng to leave her behind and go see his beloved. All Bai Xianyu gets is a photo of the two of them on his beloved's social media, reunited after a long separation. It's as if she's merely an NPC pushing their love story along.
The System says, "..."
Poor thing.
Deciding to break up isn't that hard, either. Gu Linfeng doesn't care in the slightest. He just says, "Suit yourself."
No arguments, no ugly scene at the end. They're practically a model breakup.
So even when Gu Linfeng comes begging to get back together, eyes red, she still says gently, "Let's part on good terms."
She lets him keep the last shred of dignity.
For Gu Linfeng, the gentlest thing is the sharpest blade.
A foolish son and a couch-potato mom, face-slapping the scumbag and his beloved.
Theme: You are the best mom.
