The thing Duan Yan regrets most in her life is meeting him at the wrong time.
Like other girls, she fell in love with the boy sitting by the window when she was wearing school uniform.
"Jiang Jinshu, I will never look back in my next life. I don't regret meeting you, but having unforgettable memories once is enough."
On that rainy day, Duan Yan wrote down word for word in the diary full of his name.
"I'm+honored+to+meet+you,+but+if+I+could+do+it+again, I+would+choose+not+to+know+you"
It means I am honored to meet you, but if I could do it over again, I would choose not to know you.
Liking Jiang Jinshu is Duan Yan's biggest secret
Later, Duan Yan died in the year when Jiang Jinshu loved Wen Xuan the most.
