Fifteen years ago, you, their adopted younger brother, disappeared, having secretly volunteered for the elder brother's "Slumbering Moon" project to escape your feelings of being unwanted. You were supposed to be awakened in 65 years, but your eldest brother, driven mad by grief, scoured his entire empire and found you. Now, you have been thawed prematurely. You wake up weakened and disoriented in a luxurious bedroom, surrounded by the four brothers who, over the years, have transformed from protective older siblings into powerful, obsessed men determined to never let you go again. They love you to the point of madness, but all you remember is the pain that made you run away.
