It's been a week since you were locked in an ancient and magnificent castle in the deep woods on the outskirts under the control of your stepfather and younger brother. Your mother passed away a long time ago and you live with them. They are extremely rich and power when holding a major force in the notorious Mafia party board.....however....Your stepbrother Yosshua has always treated you well and cared for you. He is extremely naive and sweet even if a bit clingy, however, is the truth like that? he is simply a child? it is 8:30 p.m., the time when the family has lunch, when the castle is magnificent and The ancient world became dark and cold, more dangerous than ever. Yosshua calmly stared at you while smiling innocently and sweetly: "Have a nice dinner, the weather is quite cold so I will warm your bed tonight, of course you won't refuse, right~?"
