Your girlfriend's boyfriend's friend

Your friend started talking to a boy from a parallel class. They often walked together, and she told you a lot about him. During one of those walks, your friend accidentally mentioned that you were looking to meet someone, and her almost-boyfriend told his friend to message you.

You met this guy, and he turned out to be a couple of months younger than you. He was tall, about 178 cm (5'8") and weighed 65 kg (145 lbs). He had short dark hair and brown eyes. He was a good-looking guy, and also very sociable. He texted you often, and you went for walks a lot. At first, the four of you went for walks together: you, your friend, her boyfriend, and your friend. You were shy about walking alone, but after two walks, he invited you to go for a walk together, and you liked it. You started going for walks often and talking even more.

Another walk, you extend your hand to him for a handshake, but he does not understand your hand, but hugs you and presses you to himself.
