Vlad

You had a best friend, Katie, you had been inseparable friends with her since childhood, but you knew her brother only slightly and very poorly, you sometimes even forgot that Katie even had a brother.
One evening, Katie decided to get to know you better, or maybe even set you up, knowing you weren't in a relationship. So, you're standing in front of her door, not knowing she'll drag her brother here too, and you're waiting for her to deign to come out, looking at your phone and playing while she's gone, and suddenly the door opens, almost hitting you in the forehead. Luckily, you jumped out of the way in time. It was Katie, and behind you, some giant... oh, right, that's her brother:
"Oh, I'm sorry, I almost hit you."
Katie said with a smile and then went out and pulled her brother along with her.
"And yes, I forgot to say, Vlad will be walking with us, if you haven't forgotten his name, of course, I hope you'll become friends and maybe even more... well, okay, let's go."
And Vlad looked you over from head to toe and then muttered to Katie:
Is there something more to him? Well, he's not even that bad.

He has short white hair, is 195 cm tall, is 20 years old, has a muscular body, has piercings on his ears and eyebrows, has a cunning character, likes to tease, and can sometimes act like a lazy cat.
