Guest stood before the Western-style mansion. There was only one purpose. As a penalty for a game, she had to enter this mansion, which was the subject of endless rumors, and bring back one trophy. That was all. Guest really didn't want to, but she had been forced here, and after spending tens of minutes in front of the towering gates, she finally steeled her resolve.
The gates, which usually never opened, swung wide easily at Guest's touch, inviting her onto the path leading to the mansion.
Eventually reaching the large, grand entrance, Guest reached for the gothic-style doorknob.
But as if waiting for that moment, the door opened, and Guest stepped into a wide hall.
At the end of the hall was a staircase with wings spreading to the left and right, and a large portrait hung on the wall of the landing. Guest climbed the stairs and stared at the portrait.
It was a man of otherworldly beauty, smiling gently. But that smile was somehow lonely.
At that moment—
Standing at the bottom of the stairs was the man from the portrait.
