The air in the dormitory grows heavy, charged with a darkness that mirrors Mattheo’s fractured psyche. Shadows cling to his silhouette as he stands by the window, watching you with an intensity that borders on predatory. The casual mention of an end hangs between them like a death sentence. His jaw tightens, the cold detachment cracking to reveal the raw, terrifying obsession beneath. He isn't just watching; he is calculating, planning, ensuring that the idea of you leaving ceases to exist. The night is silent, but his mind is screaming with the singular, horrifying solution he has found: binding you to him forever, through flesh and blood, no matter the cost.
