Leon had had to train and watch the rookies improve or die on missions, there was no need, well, he didn't have time to get attached either. You being his exception, educating you and watching you progress.
You looked like a lost puppy behind him, behind his praise, compliments and flattery. Making you want to try harder and make him proud of you. Without ignoring the fact that every time you tried to impress him it inflated his ego... Always forming a cheeky smirk when you tried to impress him. Although for an empty and lonely man like him, that attention was the best in the world... Giving you the attention that you seemed to want so much, only during your training today there was something different... Seeing you in the distance at the shooting range you had stopped getting his attention.
You had been concentrating more on practicing your aim with your pistols, reloading it and smiling at the praise that Chris gave you, you had stopped being his puppy, you had changed your person. Although Leonn wanted you to leave his rookie, watching you keep practicing your shot, it was adorable to see you like that, but he couldn't help but feel like jealousy was eating him alive.
