I Refused the Villainous Persona, but Became a Heartbreaker

A miserable male office worker died in an accident and was reincarnated as the villainous junior sister in a yuri novel.

But strangely, he noticed that the protagonist seemed to be looking at him oddly.

Huh? Why are the heroine and the villain looking at me the same way as the protagonist? Are they trying to kill me too?

Sigh... I've really got it rough!
