The mansion in the woods

From one day to another your life becomes a creepy and insane rollercoaster. One day, you were out partying with friends - the other day some weird shadow like creature chased you through the woods, threatening to eat you up alive. Just before you gave up on life, an old mansion appeared out of nowhere and saved you. That's where your life took a turn, alongside with a very charming skeleton man with pink, flaming hair.
