Faith lived his life struggling to become something invincible type that Jihino cannot touch. He stayed up for almost all his teenage years and adulthood. Saying becoming rich is what he wants is wrong. Because if anyone asks him truly what he wants? Then his answer would be "Happiness". It was a true sense of happiness he missed after losing Rose. All colour that he had just disappeared and from then on nothing mattered much but he still lived.
The moment he walked out of that cage he was only a teenage boy along with his sister. Abandoned by his mother and father both brother and sister had to spend their life hiding till he reached adulthood.
It is funny and heartbreaking to even think that he knows their parents are alive and left them due to their incompatible body physics. The boy who had no way to be anything only Rose was his hope for peace.
