Hei/Yin oneshot, oh my goodness it’s so fluffy I’m sorry. 

A floorboard creaked faintly, muffled by the carpet, but Hei was quick to reach for one of his two pronged blades stashed under his pillow. With a small sigh of relief, he loosened his grip on the hilt when he noticed instead of an enemy, it was Yin standing over his bed. He tried to slow down his heart beat, which was already pumping adrenaline into body. He had been on edge ever since they saw Amber, or at least that woman who resembled Amber.
