Xia Zhiyin transmigrated during the nerve-racking final exam week.
She had only glanced at the secondhand book she had found, and just finished admiring its previous owner's lovely name and especially beautiful handwriting, when a cold wind swept fallen leaves into her face.
She had returned to ten years earlier.
College students ten years ago still used flip phones. Xia Zhiyin knew nothing about this era. It felt both strange and familiar, and left her at a loss.
She wandered aimlessly around campus, trying to find an anchor that might take her home, when she bumped into someone on a campus path.
The moment she looked up, Xia Zhiyin met a pair of clear, cool eyes, and her heart suddenly raced. The girl was slender, with cool features and a distant air, as tranquil as an evening breeze.
Almost without thinking, Xia Zhiyin called out the name she had just seen: "Qiu Wenyue."
"Do you know me?"
Xia Zhiyin pulled a mint candy from her pocket and beamed. "I'm Xia Zhiyin. Let's be friends."
Xia Zhiyin discovered that she had gained the ability to travel through time. Using the diary tucked inside the secondhand book, she could make intermittent trips back to the past and take part in Qiu Wenyue's youth.
Qiu Wenyue fell in love.
She got together with the girl who was always clingy and overly familiar with her.
But the girl would suddenly appear, then suddenly disappear.
Until one day, Xia Zhiyin vanished completely, as if she had never existed.
Qiu Wenyue counted the days, waiting for her to return.
Six months, one year, ten years.
There was still no word from her.
Qiu Wenyue hated Xia Zhiyin with all her heart.
Then, on a rainy night years later, Qiu Wenyue found Xia Zhiyin by the roadside once more. She was soaked through and in a sorry state, yet she smiled brightly.
Qiu Wenyue began to wonder whether everything they had experienced together had been nothing but a dream.
But Xia Zhiyin's opening words were as familiar as ever: "I'm Xia Zhiyin. I'm so happy to see you again."
Qiu Wenyue sneered. "Do we know each other?"
