what is this rose I had rose because they makes people happy and I don't like things that make people happy because I am nemesis. I am the goddess of all things unhappy and since roses make people happy I will put a curse on these that if someone touches these rose they will mean to anyone they love and care about.
Aphrodite found out about the curse because as she was looking over the balcony at olympus and saw all the people fighting with there love ones and the people they cared for she realize that they were all under a spell and she found out that the roses that she had planted were curse and she know that the only on that could have cursed the roes was nemesis the goddess of unhappy things and she know she had to break the curse.
Aphrodite reversed the curse and put a new spell on the roses. It made people apologize for their yelling and treat everyone nicely and then nemesis knew that her curse was broken and she was unhappy and then she was not happy and she wanted more revenge on all of olmpus.
