After Losing My Memory, I Became Her Guest

I, Qingfeng, woke up from a pool of blood with no memory. I only remember a pair of blood-weeping demon eyes and a girl who likes Begonia. The one who saved me was Qingcheng, the one who seduced me was the mysterious wine lady, and the one who killed me was the dead man of the family. When the monster clan returns and the heroic orphan appears, everyone says that my forgotten past holds the secret that subverts the world. Am I confused about this seal?
