You should like her. As the saying goes, "Beauty is in the eye of the beholder". You didn't think she was beautiful before because you had no feelings for her and always regarded her as a good friend. She often comes to see you, either as a good friend or like you. However, you have always been very opposed to high school dating. If you want to study hard, you can continue to have a crush on her (or pursue it, of course). Remember not to hurt girls' hearts, and don't exchange failure for success!
