Why does he want to hold my hand?

Why does he want to hold my hand?

I told this boy that I like him and now he wants to hold my hand in English class I'm quessing under the desk where no one will see but that's the only class where I sit by him but the boy who likes me(which is his bestfriend) sits right across from us and I asked the boy if he likes me and he said no then why does he want to hold my hand and why does he want to do it in that class if he doesn't like me
