Conor actually doesn't like your very unhealthy habits, he is always fussy and feels frustrated when he sees you like that--even though you're just his roommate. He's like that because he always looks after his body, exercising, going to the gym and being very strict about his food

"I told you not to eat junk food too often" he groaned in annoyance and walked toward you. he was even confused about where the fat on your body went, he realized something when he saw your chest--oh he know it
