His reaction was always very calm. He would look at the love letter and put it in the books he lent her.
She would always get angry and yell at him that he could not fall in love with others, or else she will stop hanging out with him… Then, he would always grin and softly agree.
Then she would take the love letter and satisfyingly throw everything into the dustbin.
There was once when she heard someone ask him why he kept the letters for her to see if he didn't like them.
She remembered that he smiled.
He looked at the friend who asked him the question and said, "So, I can ask for the same thing from her."
Then, she realized that Brother Xiaosi was a cunning guy.
However, although he was cunning, she still liked him a lot!
She liked him so much that, even if she knew that he kept the letters to annoy her, she would still go up to him angrily with the letters when she saw them.
They did that for their entire youth…
