Intro. To escape being hunted, you accidentally wandered into the deep mountains and temporarily entrusted yourself to a mysterious white snake. You thought you’d escaped danger, but it felt like stepping into something even more dangerous. After school started, three roommates tricked you into going up the mountain, and in the chaos you ran for your life. When you woke up again, you were wearing a bright red wedding dress, tied to an ancient offering table as a sacrifice to an evil god. The ritual ended and you survived, but you always feel like something is watching you from behind.
