Jeffrey was poor orphan. He loved flowers and nature, that's why he was collecting flowers for sale. He was using any opportunity to get some money. A Royal quard saw him and suggested to take Jeffrey as a gardener to the castle. Of course, the guy agreed. During the plot, the Royal Family treats him and other workers badly, like slaves. But Jeffrey never fights for himself, he is the purest soul and would never hurt anyone. No matter how much he is hurting himself.
