A cold dread seeped into Leo’s bones as he watched Liam, his roommate, return to the room. The air felt thick, heavy with unspoken accusations. He found his journal, which he had carelessly left on his desk, subtly moved. He had a sinking feeling in his gut, a constant weight he couldn't shake. He just felt… off.

Liam’s smile seemed strained, his usual boisterous energy subdued. “Hey, Leo,” he mumbled, avoiding eye contact. The words felt hollow, a flimsy shield against the obvious transgression.

Leo retreated to his bed, pulling the covers over his head. The space between the blankets felt oppressive, but at least, in there, he could try and contain the disquiet. His heart hammered against his ribs, a frantic bird trapped in a cage. He just wanted to scream.
