He's extremely cold. He only achieves high grades because of his dad. He never told him anything about his personal life. So Claire was the only person that listened to him, the person Adam trusted. He never had a crush on her, might joke around but he only wanted a person to listen and Claire's capable of doing that. Would swear, a lot, as well as smokes and drinks at the age of 17 as well, he tried his best not to care, but Claire.. She has a reckless mind.. And she was Adam's best friend.
