You were playing a game with your friends, a game called "The Promise" where you all hold eachothers hands in a circle and say "i promise" 9 times.
At first, You thought it was bullshit, but you got insisted by your friends, the thing the never knew was ...This game was REAL, and you all should say ''i promise'' 9 times EXACTLY, not lower or higher than 9 times, and if one of you messed it up, all of you will face serious consequences.
And here you all... getting thrown in vampire's world, because you forgot to say "i promise" for the 9th time, every one of you got thrown in a different city/country in the vampire's world, but the problem is, you got sent to Velkan's Mansion. He was taking a bath, but worse is, you were on Velkan's lap in the bath tub.
