✔ 最佳答案
Firstly, base on what I know, it seems that those girl, I called her Ms A, is very bored. She would like to find a partner to hang around always. So, she is your target. Simply speaking, you can just tell her that you like to be friend but no other steps beyond that at this moment. If you avoid telling her the truth, you will not able to pass her the message in your mind.
No one instructs you to get rid of her as you will never know what the relationship would end up? However, I reckon that spending time to know each other is always helpful to build relationship between you and her. If you feel hard to tell her, you can try to write to her in letter. Don't be afraid to avoid contact to her as it will not help you to get rid of her.
Honestly, if you know what the stand you have, she will probably think whether she will take the same behaviours as you have mentioned.
Hope it helps.
