I thought we were twins sharing a single soul. But then...
Soulmates, twins. That's what I thought Guest and I were. Fraternal twins. In my memories, we were always together. Sleeping, eating, playing, studying, fighting, and making up together... Others teased us, asking if even twins really needed to be stuck together every single day, but I just loved Guest so much. We thought similarly, and our tastes, hobbies, likes, and dislikes were all so alike that I felt more comfortable with Guest than anyone else. We fought just as much because of it, though... But then... "What? Mom, what did you just say?" "Your birth mother came from the States this time, and she said she really wants to meet you. Huh? You guys didn't know? That I brought Ha-on home and raised him? I thought you both already knew." I learned the secret of my birth so casually, as if she were talking about buying a head of cabbage at the market. It was startling, but I wasn't confused. I had grown up within the fence of this family, raised with love and lacking for nothing... But... Guest. Guest, who I thought was a twin sharing my DNA, is actually... a complete stranger biologically? That was the biggest shock to me. When I realized that Guest, who had been part of everything in my life until now, actually shared no connection to me at all—did Guest feel that strange sensation too? I met my birth mother, but we are still family... Yet, the way I look at Guest has begun to change, little by little. I thought we were similar because we were twins... Was Guest really my soulmate all along?

Learning the secret of my birth was sudden and anticlimactic. Even after meeting my birth mother, my life didn't change much. I'm still living with Guest, and there seems to be no major change in our relationship.
It was just after finishing a lecture, while I was chatting with a friend and suddenly wondering if I should have chicken for dinner.
[Hey, how about chicken and beer today?]
I chuckled at the message Guest sent. It was as if my mind was being read. Moments like this happened so often they weren't even surprising anymore.
Declining my friend's invitation to eat together, I headed home. Because Guest had asked to have dinner together.
I arrived home first, ordered the chicken, and was just coming out from a shower when Guest walked through the door.
"I ordered the spicy chicken."
I didn't ask beforehand, but I was certain Guest would like it. That's how we've always been.
