Three years after marrying Gu Yuan in a whirlwind wedding, Chi Yu unexpectedly travels back to his student days.
She sees with her own eyes that her once-refined, elegant husband can now take down three burly men with his bare hands and barely break a sweat.
Even his neat, dark blue school uniform can't hide the chill emanating from him.
As Chi Yu stands there dumbfounded, Gu Yuan notices her.
He wipes the blood from the corner of his mouth, says nothing, then looks away and walks off.
Chi Yu has heard Gu Yuan say that when he was in school, his parents didn't care about him, he was rebellious and hard to tame, and everyone was afraid of him.
Thinking of how considerate and protective Gu Yuan is toward her after marriage, Chi Yu decides to return the favor and take good care of the Gu Yuan of this era.
Gu Yuan likes Chi Yu.
But Chi Yu is obedient and well-behaved, a good student at a top high school. She would never associate with a rebellious delinquent like him.
Gu Yuan never expected to have anything to do with Chi Yu.
But suddenly, one day, Chi Yu starts showing up in his life all the time.
When he gets sick, Chi Yu brings him medicine;
when his blood sugar drops, Chi Yu brings him breakfast every day;
when he takes a day off, Chi Yu lends him her notes...
Gu Yuan: "..."
One day, Gu Yuan gets hurt, and Chi Yu rushes to his home. Without a word, she starts taking off his clothes to look at his injury.
As Chi Yu's wandering hands make his ears turn bright red, Gu Yuan grits his teeth to keep his feelings under control, pushes her out the door, and tells her not to come back.
After they marry, Gu Yuan is incredibly gentle and never loses his temper with Chi Yu. But the Gu Yuan from his student days is actually mean to her.
Feeling hurt by the contrast, Chi Yu sits curled up with her arms around her knees beneath the streetlamp outside Gu Yuan's home.
Suddenly, a tall figure blocks the light above her.
Chi Yu looks up.
Gu Yuan hands her a tissue, his ears so red they're practically dripping blood.
"Don't cry."
"Fine, you can look at it."
Chi Yu is a quiet, reserved girl. Even though she gets excellent grades, a top high school is full of outstanding students, and she never stands out among them.
It isn't until she returns to her student days that Chi Yu realizes that during all those ordinary days she remembers, someone was secretly and passionately in love with her for years, in a place she never knew about.
"You thought you fell in love after we married. The truth is, my long-planned crush finally came true."
