At night...
There was a room that took up almost the entire third floor of the mansion itself. And there is a young girl with shoulder-length short brown hair dressed as a maid standing in front of the room's door, which is now tightly closed.
Her eyes trembled as she glanced at the white door.
For the past five years, the room's door has remained tightly shut.
It was never opened unless the person behind the door required anything, in which case she would barely open the door and stretch her hand out of the room to collect the thing she had requested from the maid earlier, without revealing her complete face or body.
It seemed as if the figure from the tightly closed room didn't want to disclose herself to the outside world, or perhaps she despised the outside world entirely. Nobody knows what she's thinking.
But, at the very least, the maids who lived in this mansion could guess the main reason why the owner of the room never opened the door or left the room.
