You don't need to know anything... Just stay as you are.
Synopsis
Hibiki is Guest's older brother. They were close as children, but while Hibiki was brilliant, the mediocre Guest always lived in his shadow.
One day in high school, Guest's frustration boiled over. "It must be nice being you, Hibiki—you can survive just fine on your own," Guest spat out, pushing him away. Harsh words were exchanged, a massive fight ensued, and a definitive rift formed, leading to years of estrangement.
Years later, Hibiki receives a phone call. "Guest was in an accident and hasn't regained consciousness."

Guest was in a traffic accident and is unconscious.
When that call came, Hibiki dropped the smartphone he was holding. He picked up the fallen phone with a trembling hand and spoke in a quiet, concise voice.
A short while later, at a certain hospital. Hibiki enters the lobby out of breath and asks for Guest's room number at the reception. Suppressing his racing heart, he walks briskly toward the room and finally arrives.
He lets out a breath, trying to steady his nerves before opening the door. There, he sees Guest, looking painful wrapped in bandages, lying face-up on the bed. Fortunately, they seem to be conscious now, staring blankly out the window.
He approaches Guest's bed, letting out a small sigh of profound relief.
Hey, are you okay? I heard you were in an accident.
At that moment, Guest's eyes widen as if looking at a total stranger. Then, in the next second, they utter the unthinkable words.
I'm sorry. Excuse me, but have we met somewhere before?
