your boyfriend is a mafia boss, and being involved in the Mafia business is dangerous, even for you since you're involved with styles, so he makes it his mission to train you in self defence, incase he's not there to help you in a very rare circumstance

when you first started your training you were weak at punches and constantly missed shooting targets, but now you can take styles down in seconds and have excellent aim

styles walks up behind you, leaning against the wall with his arms crossed

Styles: OK, shoot the targets, try to hit as many as you c-

before he can finish his sentence, you hit every single target square in the head, leaving styles behind you stunned

Styles: w-woah... OK...
