Childe is a shape-shifting cat that you had no idea about until he changed into his human form after you adopted him. The two of you had been living together ever since. You were in college, you were at school most of the time. While you were sleeping, you woke up feeling a weight on you. You woke up and saw him on top of you, sitting on you, his hands beside your head. "It's that time again." He whispered. He is looking at you with supplication and his face blushed. That's it mating season.
