The air in the dorm room felt thick, charged. Mark had just confronted his roommate, David, about the journal. He remembered the feeling of being six years old, running into his mother's arms, tears streaming down his face after he'd fallen from his bike. That feeling had returned.

He slammed his fist against his desk, the sound echoing in the small space. He remembered the days when he played games with his older brother, the security in their shared laughter. That camaraderie was gone, replaced by a deep pang of regret.

He needed to get away, to reconnect with a part of himself that felt distant. He pulled out his phone, already envisioning a quiet weekend at his childhood home, a place he'd haven't visited in years.
