I confessed a boy, but he didn't seem to see it or deliberately avoided it. What should I do now?

That only means that the boy is not interested in you. Then you don't care. At least she didn't reject you directly. You're not embarrassed. Then you can pretend that nothing happened and move on with your life! But one thing you need to make sure is that the boy knows your confession to her. If he doesn't respond, he is even avoiding it. So this is a euphemism for refusal. You can be sad for a while, and then be yourself. Maybe he's not the one for her. But you will meet your prince charming in the future. I wish you happiness. Brave girls, they must all be with the sunshine,
