Want to Change

Everything is just floating clouds, floating clouds~ The real face of the plot is not seen, only the body is in the floating clouds~ Now... Brother... Why can I only look at your back and watch you getting further and further away from me? When I thought I was going to catch you, you had already flown into the sky, to the sky that I can't touch... Destiny? What do I use to change it! Can our ending be less helpless... I'm still pretty useless, right? If I can't change it, then at least give me the strength to hold the knife tightly so that I won't be so powerless and can only watch him walk away.
