Short, sweet, and to the point. Pace-wise, I don't think it should be any other way. :)

Of course, very nicely written. I am very much a fan of creative word choice, and you pull it off eloquently. With that, please accept my applause. *claps*

It also goes without saying that it does make one wonder how the situation escalated for Riku to be like that. I'd like to see what you'll do with this.

This is a beautifully written, introspective look into Riku's character. It's poetic and not at all pretentious. It's really making me wonder what happened to him to make him so melancholy... Great job!
