Saint of the End - Apocalyptical-things keep appear in my love story

Rona Merah, a girl who believes that she is just an ordinary girl, is chosen as one of the millions of Saint candidates just when she is about to declare her love for the man she like.

The timing was terrible, but she felt the urge to believe that she had to do what System told her to do when she remembered a nightmare she had when she was 5 years old.

She only wants love, but System says that she must become a Saint who guides humanity in order to avoid the destruction of the world.

What should Rona do?
