Slay the Gods: The Nine-Tailed Fox Has Arrived, So All Regrets, Make Way

[Slay the Gods fanfiction + all pairings + two male leads + making up for regrets + original settings + OOC] Su Qi'an transmigrates into the world of Slay the Gods and even gets the System that transmigrators are supposed to have. But his true form has become an injured nine-tailed fox. He is afraid: afraid of the dark, loud noises, being restrained, and most of all... being abandoned. He believes he doesn't deserve love, peace, or even to be alive. So he atones through pain and confirms his existence through destruction. He dares not accept kindness. He's afraid of anyone getting close, and even more afraid of being held back, so he pushes them away first. But in this world, someone keeps choosing him, unwaveringly. There are several endings, including all-pairing and one-on-one routes.
