How should I reply to a blind date boy?

To put it bluntly: looking at fate, you don't want to find it, but you can find it if you want to find it. Sometimes I may miss it. Sometimes it may be that the two sides see each other right. You said that you are 22 years old and have no love experience, so I suggest you talk more (nothing else, don't make fun of your feelings) so that you can know what you need. Sometimes fate is based on the opportunities you give yourself. So, if you think that man is ok, I suggest you get in touch with him, get to know his personality and see if he is suitable for you.
