I'm not a villain!

A girl who came up in a game. Eh? Sister of one of the love interests? A villain character? So then, I really do not need to get involved in this, right? I just want to live my life, okay? A reincarnated girl who decided to ignore the game and instead enjoy her life. Author's Note: I have not yet decided how often I will post the chapter. And if you have any misspellings, forgive me, the English language is not my native language.
