Yaling and Shuqin Tao

• Yaling says Shuqin used to send her petty letters. Shuqin sent letters to other girls who were interested in MC warning them that MC was a womanizer and to stay away. Yaling was the one who didn't listen and this made Shuqin petty.
• Shuqin used to send letters containing spoilers of books she knew Yaling was planning to read, and Yaling thinks she's ridiculous.
