Isekai Otome: My Life is a Dating Sim?

Orelei Phillips was supposed to be a normal thirty-year-old woman...until she tried to save the cat in the street. When Orelei wakes up, she finds that she no longer lives in the real world, but has been reincarnated at the older sister to the heroine of the otome game she was playing before she came here. Now, Orelei has all of the power in her hands...and she knows what happens next. Unfortunately, the plot is suddenly becoming twisted and Orelei's only chance to get it back on track is to marry the secret canon character before he can get his hooks into the female lead...hopefully it works long enough for her to run off with one of the other 4 guys...
