I was in pretty deep depression. I played KH and saw that ending animation again. I wondered what Riku was thinking while he was inside Kingdom hearts. Maybe it was something like this.
Thinking in the Darkness
Aah! Let me out! Why won't those damn doors open? Here I am locked inside black darkness. Everyday it becomes harder and harder to fight back. Those stupid white doors just won't open. Why they must be white? What irony it is. White doors are holding, locking the darkness, black, away. And it comes to this again. I'm inside, where the darkness is! ... Why did I choose to stay inside? Oh…. I remember. I must punish myself. I betrayed my friends. How could I have had my trust in the darkness? I'm the one who is fool. Maybe I really should be in here, in the darkness, because of my sins. I let darkness rule my life, choose my path and now I must walk that path over. ….. I hope she is okay. I told him to take care of her. Why am I thinking of her? She is light. Pure light. Even he has his light. And that key. I can't believe I was supposed to be that key's real master. Well I'm not anymore. My heart is too weak for it. And I don't have that light. …Or do I? It's been said that everybody have their light and darkness. Everybody have their shadows, every coin have their two sides. I am same right? I must just seek and find my light! I will maybe find my key and then get out of here! But do I deserve it? … I want to see my friends again. We three together again just like in old times. After I have redeem my sins,because of my friends, because of my light, I will get out of here!
