Boys ask him for a blind date, and he uses me as a shield? What does this kind of person mean?

The boy's family asked him for a blind date, and he used you as a shield. Actually, it's a confession to you in disguise. You two should get along for a long time. He likes you, but he's embarrassed to tell you. Only in this way can you express it. It is best if you can understand his mind and accept it. If you have no feelings for him, forget it. It doesn't matter whether you agree or not to block it, and it won't affect the relationship between friends.
