I looked at the girl with my eyes when she asked for dinner. She gave me a look and immediately avoided it. She also smiled and said, "What are you looking at me for?"

It should be that she likes you very much in her heart and cares about your attitude towards her. She is afraid that you don't care about her and want to hide it, so she said that she won't let you watch her all the time. She always wants to be with you. This can be seen from her offer to invite you to dinner. If you have feelings for her, I hope you can treat her well. If you have no feelings, tell her clearly as soon as possible, and don't let her have any illusions about you, which is good for both of you. I hope you are happy.
