We are in the same class at uni and I talk to this boy a lot on whatsapp but when we met at the classroom, he won’t say anything and just smile if our eyes meet. He doesn’t really talk to anyone at class as well, just come to attend the class and go home without hangout. I once asked him to sit next to me but less than 10 minutes, he asked permission to move, and on whatsapp he told me he was shy. I don’t want to make him feel uncomfortable or force him to talk to me. So what I better do?
