I'm my younger brother. I was wrong. How can I apologize to my brother? I'm embarrassed to say it! How can I tell my brother that I can be natural and sincere?

What's embarrassing? I did something wrong. It's normal to admit mistakes. I'm sorry. It's human nature. But compared with your feelings, which is more important, face or feelings? Tell him bravely, as long as you mean it. I believe your brother will forgive you. If he were your brother, how could he laugh at you? I wish you a lasting friendship.
