What is this manga called?

It was about this girl(i think her name was Momo) who lived w/ her grandmother and she was very plain. One day her grandmother dies and she has no other family. Shes at like a park or something crying on a bench and this guy sees her(i don't remember if he appeared before this)and he takes her to what I think is his house. Anyway he cuts her hair without her consent and gives her a makeover. He tells her about the belief that some humans are the descendants of flowers and something about spewing pheromones that attract people and that they both have it. I'm pretty sure his mom is like a fashion designer. She gets kidnapped in like every chapter and it's smut. If anyone can tell me what this manga is called it would be a great help.
