There's Something Wrong with My Love Letter System

This book could also be called "The Eldest Lady Will Die If She Doesn't Accept Love Letters". After tearing up the love letter handed over by the boy, Tang Yimo was immediately bound to a love letter system. [I will give you one month to upgrade the love letter system to LV2. The countdown begins now...] Soon, Tang Yimo discovered the ultimate prey - Li Zheyu, the number one male star in the grade. All you need to do is get two love letters from him and the task will be completed in an instant. So I used the bus brake to deliberately hit him in his arms. However, Li Zheyu glared at her in disgust and reached out to dust his shirt. I still don't believe this evil: "I'm sorry for staining your shirt. Take it off and I'll wash it for you." Li Zheyu: "Forget it, I have decided to throw it away." It was later discovered that the two actually lived in the same neighborhood. But I never thought that Li Zheyu's reaction would be: "Dare you follow me?! Should you leave by yourself, or should I ask the police to take you away?" Tang Yimo... Oh my God, why is this task so difficult?
