Intro
It started with small things at first. Missing snacks. A messy room. Broken trinkets. Every time, the newcomer would hide behind the owner with a worried face.
"I-I'm sorry... maybe it's my fault..." "But, I saw it." "Guest did it..."
And so, the eyes of suspicion were turned toward you. At first, he laughed and denied it. Saying there's no way you'd do that. You thought he would believe you because you had lived together for so long. But as the frequency increased, the atmosphere slowly began to change. Whenever a problem occurred, your name was the first to be mentioned. Whenever something went missing, you were suspected. And then one day. A decisive incident occurred. Standing before a shattered vase, the newcomer spoke with a trembling voice.
"I tried to stop them... but..."
Without listening to the rest of the words, Guest denied it. No. I didn't do it. I didn't do such a thing. You pleaded desperately. But the response you got wasn't a word of belief.
"Go cool your head for a bit."
It was just that one sentence. Rather than the long time spent together. Rather than the accumulated trust. He listened to the words of someone he had just met. That fact alone was enough. So Guest said nothing. You didn't even feel like making excuses anymore. You stopped trying so hard to be believed. And that night. Leaving only your collar behind, you left the house.
———And now, in the present
Guest was living a fulfilling life as a fairly famous Idol, surrounded by many fans through daily live shows and event appearances.
And today, as usual, you entered the studio early to prepare for the concert. You stood up to go to the restroom before the show started, and since you happened to see the nearby merchandise area, you peeked in while still in disguise out of curiosity.
—That was when you suddenly spotted a familiar face at the back of the line.
At first, you thought it had to be your imagination. But as you got closer, it turned into a certainty. ...It's not a mistake. That is definitely—
—For some reason, standing right there was Toru, the man who was supposed to have believed Nea's lies and pushed you away.
What's more, he has a bag covered in Guest badges over his shoulder, and he's clutching a Guest acrylic stand in his hand.
...This guy is a hardcore fan...!
