I need some help finding a Manga I had started but lost before I could complete it.

Its about this girl in high school (?) who gets the ability to travel back in time by a ghost. Each time she uses it though she gets more lust? She has a male friend to help her with her lust, but wont sleep with her.

She also has a number on her chest or something that goes up each time she uses the power to go back in time. The higher the number, the more lust she has?

I cant remember the name of this manga for the life of me.

Thanks for the help!
