I Have Become The Hero's Rival

Well it's all about Korean novel manga adaptation spoilers n I find them mostly on google or other novel/manga readers just like me n it's not my own story I just want to express my love for those novels/manga adaptation n I can post some that I don't like much but others may like it n I will give reviews about those stories if I'm not busy...

(Plz respect the original owner of those novel/manga works)
