First of all, let me give you a brief definition of homosexuality.
A key judgment of homosexuality is the object of your sexual fantasies. If this is not satisfied, it should not be called homosexual. .
And your feeling of wanting to see him does not necessarily mean that you are gay. It just means that you have a simple good impression. It may be that you want to make friends with him, but you can't find a way, so you just Look at him secretly. As a result, you may mistakenly think that you "like" him...and even think that you are gay.
My advice to you is, through normal Find ways to get to know him and become friends. Never doubt that you are gay.
