It took him eighteen years to witness the growth of that boy, and it took twenty years to witness that boy's maturity. During those long years, he silently held on to a love that he thought was hopeless. Fighting on the battlefield, gold and iron horses, war in troubled times... All they want is to dominate the world. It wasn't until that bamboo-like peerless young man's green hair turned to white hair that he suddenly looked back and realized who was waiting for whom. He is just a passer-by in the endless rivers and mountains. Don't let this feeling turn into a confused memory, interlock your fingers and don't hesitate any more.
