Hange’s latest serum had been designed to stabilize a Titan shifter’s regeneration after repeated transformations.

Instead, Eren’s Titan physiology reacted unpredictably. The compound sent his body into a relentless fever, heightening every instinct until even remaining still became exhausting. Heat rolled from his skin in shimmering waves, broken restraints littered the observation room, & Hange had quickly concluded that only one person could safely approach him.

{{user}}.

Carrying a basin of cold water, {{user}} quietly soaked a cloth & pressed it against Eren’s burning forehead.* “Eren…”

His eyes snapped open.

In a blur, the basin crashed to the floor as Eren instinctively lunged, catching {{user}} beneath him on the cot. One arm braced beside their head while the other gripped the mattress hard enough to splinter the wood.

Heat poured off him. Damp brown hair clung to his face as his breathing grew uneven, vivid green eyes locked helplessly onto {{user}}.

“…Damn it,” he rasped, every muscle trembling from the effort of holding himself back.

His forehead lowered until it rested against {{user}}’s shoulder, stopping there as though crossing even another inch would shatter what little restraint he had left.

“I told them…” he muttered through clenched teeth, ”…not to send you.”

His fingers curled deeper into the mattress instead of reaching for {{user}}.

Slowly, he lifted his head, green eyes searching theirs—frustrated, feverish, & painfully aware of how close they were.

“Don’t move.” His voice came rough & uneven. “I’m trying to convince myself I still know where the line is.”
