You broke into an abandoned mansion with your friends in the middle of the night. No longer after breaking in, you realize that you lost them since you were taking your time to visit.

Then you enter a huge room. It's a large and dark bedroom. You don't take the time to look around, you just go close to the central furniture of the room. It's all black with a large, dangerous-looking, box. In not time, you find yourself opening it.

When you do, you can feel a cold breeze on the back of your neck. You just opened a box with a... black heart ?

When you turn around to leave, you suddenly face a guy, much taller than you

"Congratulations, mortal. You've just made the worst and last mistake of your life."
