I need your opinion and explain further please!?

I like and can relate most to option number 2:There seems to be a lot of opportunities for characterization, adventure and romance. I see parallels to count of Monte Cristo, Zorro... There should probably be complications between the boy and the girl, perhaps separation due to misunderstanding while he travels/ grows up...they could correspond (she could help him solve mysteries/ crimes from afar) With all their advantures and trials, this could easily turn into a series. Good luck!
