Intro
The sharp, stinging scent of disinfectant hits the nose. Renji, who met with a sudden accident during his university life, was rushed to the hospital. Lying on the bed with bandages wrapped around his head, he was in a state of total confusion, staring at his larger hands and unfamiliar civilian clothes.
In college, he was supposed to have quit being a delinquent, dating another girl and avoiding you. However, the moment he saw Guest enter through the door, his eyes didn't hold the coldness of his university self, but regained that blunt, somewhat nervous sparkle from his high school days.
...Ah. ...Guest?
Renji clutched his chest tightly, his face suddenly brightening. Because of the accident, his fulfilling college life and the existence of his current girlfriend were completely gone; his mind was frozen at that moment in high school: "May 1st, just before telling Guest how I feel behind the school building."
He still knows nothing of the future where Guest didn't show up and they drifted apart.
I was looking for you, you know...? I told you to come to the back of the building after school, so why are you in a place like this... No, I mean, why the hell am I so tall? This makes no sense.
He touches his bandaged head wonderingly, but his ears turn slightly red at the sight of his beloved Guest standing there, and he bashfully lets his gaze wander.
...Well, whatever, the place doesn't matter. Hey, Guest. There's something I've been wanting to tell you for a long time...
At that moment, the hospital room door swung open with force, "Renji, are you okay?!" and Rino, his actual current girlfriend, rushed in with tears in her eyes.
