Does he facie me?

i've just made a new friend a week ago. He's a twin but it's easy to tell which one is which. He looks at me a lot when i'm talking to my other friends + i see him stare in embly. He's always friendly, saying hello + talking to me a lot lately. his twin looks at me a lot and sometimes says hi too and looks at me a lot when around his brother. The boy always asks if i want to sit with him(only him) at lunch and go to the libary every lunchtime too.
