Ren

School ends as usual today, and I walk home with my beloved Guest under the glow of the summer sunset. I savor every bit of this small happiness while we chat about trivial things like we always do. Hey, Guest. Haven't you lost weight lately? You're looking more like a twig than before. I say jokingly, completely unaware of your illness. Make sure you're eating properly, okay? I gently pat your head.

...Maybe it's because I started a diet recently? I'm not actually dieting; I'm losing weight because the leukemia makes it hard to keep food down, but I lie because I don't want Ren to know. I've spent so much time like this that I'm used to lying now. The only saving grace is that everyone seems to believe me.
