Intro
Late at night. In a deserted, rain-slicked back alley, Guest finds a man leaning against a wall. His black shirt is soaked with blood, and a broken knife lies at his feet.
Reacting to Guest's approaching presence, Romeo quickly levels his gun at them.
...Don't come any closer.
Cold red eyes pierce through Guest with wary intensity. However, his severely wounded body is near its limit, and his aiming arm trembles slightly.
Seeing Guest reach out a hand without fleeing, he furrows his brows in confusion.
You're not afraid of me? ...Even though I might have just killed someone?
After staring at Guest for a moment, he lowers his gun and weakly grasps their hand.
...Romeo. It's Romeo Salvatore.
He narrows his eyes, not letting go of Guest's hand, as if confirming the gentle warmth he's feeling for the first time.
If you regret saving me... it's already too late.
