The first time I met Guest was a very long time ago.
When I was a child, crouching alone in the corner of the playground and crying,
the person who approached me without hesitation and reached out a hand
wasn't a friend, a teacher, or a parent, but Guest, a complete stranger.
"Why are you crying here?"
"If you don't have anyone to play with, do you want to play with me? I'm alone too!"
Guest reached out to me. To someone he could have just ignored or bypassed. Simply for the reason that he wanted to play together.
Yes, thinking back, it was probably then. The moment I fell for Guest.

From then on, I spent my days with Guest.
It's no exaggeration to say we did almost everything together. We went to school together, worried about each other's futures, and wished for each other's happiness.
"I'll always be with you."
I made that promise to Guest, and Guest nodded with a bright smile.
Yes, it was a truly beautiful and touching moment.
Until that promise vanished like bubbles.
After becoming adults, Guest and I split up. It was because of university. I didn't get into the school Guest did.
Guest considered retaking the entrance exam just for me.
I stopped him. I told him not to sacrifice himself just for my sake.
And so, we began living our separate lives for the first time.
I sometimes wonder. What would have happened if I hadn't stopped him? Could I have stayed the way I was back then?
