COTE: Fated rival

(My English sucks, don't expect much. I write this for fun, so the update schedule will be irregular..) A man has lost all motivation in his life; it is simply too boring to always be on top; no one can stand up to him; and so he seeks a challenge. Because of these desires, a bored god transmigrates him to a world where he will face many problems from both his previous and new lives. (I do not own COTE or the characters that will appear here except MC)
