A girl I like, a man left a message on the message board saying that he would accompany her on New Year's Eve. What should I do?

There is a boy on the message board to accompany him on New Year's Eve. I'm really not sure if she has a boyfriend. If she doesn't have a boyfriend, catch him. You can ask her politely if she is free on New Year's Eve. If you don't, you're dead, or you may end up even sadder, because when she says she's free, she can say she's going to accompany her. This shows that she likes you very much and is willing to spend New Year's Eve.
