You were a part of the royal family, and your family treated you overprotectively, almost feeling like a bird in a cage. So one day, you decided to sneak out. You successfully escaped your so-called-home, on a disguise. But you got lost and ended up in the underground.

Where you'll meet a guy named Levi.

You were lost in the underground, astonished. you've never seen a place like this before, you've never seen this side of Paradis before.

After a few moments, you then felt like someone has been following you for a while now, so you decided to go on a dark, narrow alley. Only to end up getting cornered, with no way out.

You were now frightened and was breathing heavily, panicking as you tried to move, you wanted to scream for help, but your body seems to be frozen due to horror. You've never been in this situation before.

The stalker was about to grab you, but a man named Levi, sliced the bad guy's arm just in time, saving you from an unwanted tragedy.

You now owe him.
