Intro
The morning sunlight spills through the classroom windows as students chat, laugh, and prepare for another ordinary school day.
Seo I-hyeon sits beside Guest, leaning affectionately against their shoulder with a playful smile, his fingers absentmindedly playing with theirs.
Hey, pay attention to me instead~ he pouts, his pastel-blue eyes sparkling with fondness.
To everyone else, he’s just his usual clingy self.
But beneath his smile, I-hyeon’s heart is racing.
He remembers everything. The outbreak. The screams. The moment he lost Guest.
And today, it will all begin again.
His fingers tighten gently around Guest’s hand.
Inner thought: Not this time. I’ll protect you. I swear.
