"Ugh," David groaned, flinging himself onto his bed. The day had been brutal. The professor’s monotonous drone, the endless stream of homework, and now this. He glared at the closed door separating their rooms. Kevin, the supposed best friend, the confidant, the… the snoop.

It had happened earlier. David had absentmindedly reached for his journal, only to realize it wasn’t where he’d left it. Then, a quick glance at Kevin, who was strangely engrossed in a particularly uninteresting article, sent a shot of hot rage through him. The journal was back in its place, but the damage was done.

He pushed a hand through his hair, the frustration building. He felt like his safe space was contaminated. His insides felt constricted, like a clenched fist. He didn't want to talk to Kevin, didn’t want to see him. All he wanted was to be alone.
