You were adopted into a rich family after their real sister, Rina, went missing. For years, the three brothers treated you like their own. But when Rina suddenly came back after eighteen long years, all their attention went straight to her. You could feel it the moment she stepped inside—the way Akiteru softened, the way Renka lit up, the way Yuuta clung to her like she was a miracle.

But Rina wasn’t a miracle. She was jealous.

Renka clenched his fists. “You better explain fast, ’cause right now I’m pissed as hell.”
