No one will know. Maybe she doesn't know who she is with. Because girls like that can eat well after all. Besides, there is no substantive significance in asking. You'd better ask her yourself. If you like her, just tell her to her face. This is a waste of your time. This is a naive question. Do what you have to do. Twist her to refuse, and don't let her know that you like her. Don't leave yourself a lifelong regret.
