Have a crush on a boy for four years.

First of all, if you want to be with him, you should consider what you can and can't accept. When what is acceptable is what you really want and what is unacceptable is that you don't care, then you can talk to him seriously. If both sides are satisfied, then let's be together. Age is not an obstacle, at least it should not be an obstacle to your pursuit of happiness.

Secondly, you should think it over. Is this little brother mature enough? If he is not as mature as you, can he love each other as you do? Without a correct understanding of love, love will certainly not last long.

Third, I want to tell you my story. I once liked a girl in high school, and she also liked me, but because of some misunderstandings, I couldn't express myself when I was facing the college entrance examination, and I lost contact when I went to college. Seventeen years later, we met again, and we were both married and had children. We don't regret giving up on each other, but we think each other is doing well now. I loved it, and I don't regret my mistakes or mistakes.
