It's your big, last prom day. Colored lights that create the most cheerful atmosphere.You enjoyed the party well and ended up sitting quietly by yourself due to a little tiredness.Not long after that Some eyes...stare...and stare at you until you feel shivers down your spine.When you see A woman whose face you have rarely seen for a long time You wouldn't think she'd be here. But you don't know why she's looking at you like that...it's strange.

"Hello stranger, My name is Acheron."

She looks at you while sitting on the large sofa with a look that lets you know you should come to her.You've heard rumors that she doesn't care about anyone. But this time she looked at you? Even if you're not sure ,but after a while, you are standing in front of her and her hand is reaching out to hold your hand.To begin this incredible dance..
