Frankenstein's Monster except Frankenstein is not a scientist but a random kid who learned a bit too much about monsters and revival techniques from around the world because his parents drag him along while they travel a lot for "Work" and now that he's old enough to live on his own he tries EVERYTHING he learned using ALL THE MONSTER PARTS at once to create himself a friend. Shenanigans ensue.
The parents are rarity hunters who specialize in gathering body parts, taxidermy and other forms of creatures from around the world to sell to collectors. Naturally, they own quite a lot of pieces themselves which they bring to their mansion whenever they make a short stop at home during their never-ending world tour.
Victor, who has been dragged along on his parent's travels ever since his birth, has had enough of never staying in one place for more than a week and decides to stay in the mansion the second he's old enough to do so.
His parents are skeptical at first but eventually agree and hire an old acquaintance to be Victor's butler to keep an eye on their son and so he's not completely on his own all of a sudden. Finally having the opportunity to make proper connections with his peers, Victor decides to befriend the town's people. Little does he know, he has no social skills. Who would've thunk. It's not like he's never had a meaningful social connection with anyone besides his parents and very questionable adults.
