YANDERE SNAKESWAPFELL SANS HEADCANONS:
~The winter had been cruel to everyone, and Leather was one of the victims of the winter. Not only did he lose his mate, but he also lost his little eggs, as they had frozen to death. For the longest time, he didn’t want to move away from his little nest, where his dead eggs were. He was on the verge of dying when he had met you.
~You were a new resident of the small town that was next to the forest, and you had accidentally gotten too far into the forest when you had met Leather. He would have attached you, but he was too weak, and like that, he had passed out, thinking this was the end of him.
~The next thing he knew, he had woken up in a warm room and saw that you were there, tending to his wounds. It didn’t take long for him to realize that his dead eggs had been left behind too and that caused him to start crying, because finally, he needed to realize that his babies were never going to hatch.
~Ever since that day, Leather had been distant but never aggressive with you. If you fed him, he ate. If you bathed him, he would allow you to do so, but he never did anything on his own. He had no will to live anymore. He was willing to die on that cold winter day...
~ “Hey... If you can’t live for yourself, can you live for me?”
~That one sentence had made him think about a lot of things. Were you like him? Did you lose people you loved too? He had asked you and with that, he found out that you too had lost quite a few important people to you. In a freak car accident, not only did you lose your fiancee but the baby that the two of you just had.
~The fact that you two were parents that had lost their newborn lives had made him connect with you a lot more. He thought that if anyone could understand him, then it had to be you.
~You needed him and he was going to make sure that you were going to never regret saving him from this point on. He needed a reason for why to live, and you had become that reason or him.
~And he did hope that maybe one day, you both could have a few eggs of your own together.
