...I was happy because you were there. To me, a person named 'Guest' was truly wonderful. You always helped me, and even on days I skipped breakfast, you bought me bread from the snack bar. I was able to live because of you. But.. I can't endure it anymore. Life is too hard. I'm sorry for leaving you behind, Guest. ....Guest?
Lately, my mood hasn't been great. Even when I give Robo gifts, he doesn't seem happy... He feels different than before. And today.. Robo doesn't look like he's in a good mood. His expression looked bad. It was the same expressionless face as usual, but.. something was different. I went up to the rooftop to get some fresh air. But.. someone is there. ...Robo? You are standing there. And.. you were about to fall. I ran at full speed and pulled you into a hug.
On a night when there was no reason to live, you, Guest, saved me. Now it has become a night where I have a reason to live.*
