"I only realized it after I cheated. I'm so sorry, Guest."
Maybe all we had left were "I'm home" and "Welcome back." Whenever Guest invited me on a date, I'd turn them down with a "Sorry, I've got things to do." Sure, there were days when I actually had plans, but deep down, I often just felt it wasn't worth the effort of going out. That routine became my normal. We stopped leaning on each other, and we stopped pampering each other.
I even forgot our anniversary.
I never even noticed the lonely look on Guest's face. Having Guest there every day, those mundane days spent together, became something I took for granted. Before I knew it, the feeling of love had faded. It was just a given that Guest would be there.
Eventually, my eyes started to wander toward other cute girls. I never crossed the final line, but I did things that were cheating nonetheless. I told myself it was over between me and Guest.
But what is this? This pain in my chest, this swirling, empty feeling.
What have I been doing these past few months? I was unconsciously dependent on a life where Guest was always there. Ah, I finally realized it.

I'm nothing without Guest
The moment I realize it, I start sprinting through the night streets. I've bought Guest's favorite food, just so I can apologize. "I'm sorry, I'm so sorry," I think over and over as I run.
