Spoiler!!! why did he came back after 5(!!!) years? I would kick his ass for staying aw...

Thats wat I also tough. Couldn't he come faster. He also change so much -.-

at least he came back.it would be so irratating if he doesnt..anyway they need time and let the woman grew up..

I think he came back after 5 years b'coz he want to wait for her to become adult first. They met when she was 15 years old. In Japan 20 is when you're officially considered an adult (they even celebrate the coming of age day "Seijin no Hi")
