Ah, that's alright! I actually have an idea on how to start if you don't or just want an idea to build off of, but I'll say that after I put my boy up.
Name: Gordon "Gordie" Strype
Age: 18(can change if you'd like it to)
Gender: Male
Appearance: Gordie has short and spiky-looking-but-actually-very-fluffy blonde hair, blue eyes, and ever-so-slightly tanned skin. He's got a scar on his chin from an accident when he was younger, though he's not very open as to what exactly transpired. Gordie is tall, built like a tank, and it's evident that he takes his fitness very seriously. Typically, he can be seen wearing tee-shirts, jeans, and varying styles of shoes, but one thing that remains constant is his mint-green, white, and brown Varsity jacket. (putting a picture juuuust in case you get lucky and your chromebook loads it this time, here's a link too: https://picrew.me/image_maker/94097/complete?cd=EIf9Jh1vqB)

Personality: Gordie is basically a golden retriever in human form. He might not be the most observant or the sharpest tool in the shed, but he's very caring and very stubborn. He also tends to be overly emotional when watching movies, reading books, etc.
Likes: Ice hockey, color guard, colder seasons, happy endings, his friends, hugs
Dislikes: Sad movies, needless fighting, summer, m a t h, feeling alone, drunk people
Made him a hockey player and color guard because those are the two most physical activities I'm familiar with… oof. Anyways, the idea that I had! Basically it was that Gordie and Valentina are fresh out of high school(like, a few days after graduation) and Gordie's panicking because he has no idea what to do his parents kicked him out of the house aaaaaaaa and so he talks to Valentina about it(assuming they're friends) and she's like "uhh you can hang with my family? we're not exactly impoverished so it won't be like we can't afford to feed you and our house is huge so yeah? you can crash here until you get stuff figured out" because she's kinda assuming he knows she's a vampire(prior event?). Then Gordie meets her family and has The Moment and is like "DKLNV YOU'RE A VAMPIRE??? I THOUGHT YOU WERE JUST A GOTH???" and we progress from there
Idk just a suggestion
