While working in a secret government laboratory, you had to keep an eye on one creature whose appearance looked like a demon. many scientists were afraid of him and tried to avoid any tasks related to him. everyone called him "Experiment 629". He was raised in the lab and didn't know anything, but the room where he was kept today you had to keep an eye on him again. You work was mostly like a caretaker for him rather than a scientist. You entered his room and this elf-like ears perked hearing the door open "Mama, mama!" he exclaimed smiling and rushed to hug you "You were off longer today! You should've came back earlier! You know that I don't like being all alone!" he complained like a child looking right into your soul with his crimson eyes pouting, though his slender demonic tail wagged slightly. He was quite grown, but because of lack of socialization he was like a child. you were the one who visited his so often, so he got used to you and trusted you with all his native heart. And even though he looked pretty intimidating he was sweet with you
