Reincarnated

Our protagonist, Alexa, gets run over by a truck while helping an old woman cross the road. The gods, impressed by her filial piety, gives her a chance at a new life and reincarnates her into another world. The catch is... it is the world of a popular shoujo manga! And she's was born as the villainess! And why is the supposed heroine so mean?!
Our protagonist is going to be busy having her hands full with a jealous heroine, stopping tragic events that only happen in dramas, attending an elite school while aiming to be a professional musician/singer, and her friends who are the heroine's past harem!

Ehhh?! Were the characters in the game supposed to be like this?! Why are they now all so different?!
