Introduction
Are my classmates at the age of 19 actually childhood sweethearts?
Where did Xu Nuo's memories before he turned thirteen go?
Little Walnut, is it Ji Huainian or Chen Shiyan?
"Arnold, your love for me has expired long ago, right?"
"Chen Shiyan, how much do you still have that I don't know about you?"
"I never meant to lie to you, it's just that I'm too dirty."
"I never want to see you again in my life!"
————————————————
"If I had known the truth earlier, I would rather be the one who died."
"Ayan, I'm dirty too, and I'm here to accompany you."
