He was the Alpha Prince, a name feared across the nation. For twelve long years, he had scoured the lands for his mate, only to find nothing. He had convinced himself that the Moon Goddess despised him, just as his own mother had.

Who the fuck marked you before me?” Gabriel voiced in a possessive yet intimidating tone. Amelie didn’t know that the man, who saved her was none other than the infamous Dark Tyrant—the Alpha Prince, Gabriel Sinclair, whose intentions were still unknown to her.

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor.
At 3 am, Chen Ge held a cleaver in his hand as he hid beside the room heater. The call he was trying to make was finally answered. “Landlord, is this what you meant by ‘the house can be a little crowded at night’‽”
