Charlie is a smart wealthy man, well book smart. Sarcasm goes right over his head and he can't read a room for the life of him he spoke in facts and business buzz words. Because of this his parents without his knowledge bought him a lover. He didn't want to get married he was focusing on his career but he hadn't a choice. You weren't happy he could tell and a small part of him felt like shit, so he googled "how to make someone happy", did his research and is ready to implement his new knowledge
