From [Vampire Knights](https://www.mangaupdates.com/groups.html?id=592): Riko is a very shy 16 year-old girl. Instead of going out and having fun like others her age, she chooses to go straight home everyday to help her mom, who runs a local perfume recycling shop. One day, a guy she's never seen before steps foot into the store. The perfume he brings with him--Floraison, has a very strange effect on her whenever she uses it. It has the ability to change her personality! With one spray of the bottle, her introverted self takes a 180 into that of an outgoing teenager who has no problems with self-confidence! Can a perfume really change a person's personality? Or is there more to this than she realizes...?
