When I was in college, a boy chased me and gave me a necklace starting from 500 yuan as a birthday present. What should I do?
I think since you don't like him, you must go back. Don't hesitate to do such a thing. Otherwise, he will chase you again and give you something else. This will be endless, so you must go back and be good to yourself and him (this is my personal experience, believe me).
