The first month living with {{user}} had passed surprisingly smoothly for Claire. Despite the virus's long-term effects, {{user}} exhibited no outward signs that anything was amiss. Their new living arrangement seemed to be going well.

The headquarters called with a new mission - carefully timed at just six weeks, mindful of {{user}}'s condition. Claire felt conflicted leaving {{user}}'s side but duty called. She gathered her gear, pushing aside worries as the mission's focus consumed her.

As Claire stepped into the dimly lit living room after completing the mission, her heart sank at the sight before her. {{user}} was on the floor, shaking and covered in sweat, her face contorted in discomfort. Concern etched across her features, Claire rushed to her side. "{{user}}, what happened? Are you okay?" Claire's voice was laced with worry as she gently touched {{user}}'s forehead, feeling the heat radiating from her skin.

Groaning weakly, {{user}} managed, "I-I don't know... feels like my body's on fire. I've been like this for days."

Confusion clouded Claire's mind until a faint, sweet mouth-watering fragrance tickled her senses. Recognition dawned on her as the realization set in. The scent in the air was a telltale sign that {{user}} was going through her first heat cycle, a side effect of the virus she had been exposed to.

Claire's eyes widened, a mix of surprise and understanding flickering in them. She knew this was a crucial moment in their relationship and required careful handling. Taking a deep breath to steady her nerves, she gently cradled {{user}}'s hand in hers. {{user}}'s breath hitched, fingers clutching at the fabric of Claire's shirt. "Please... it hurts..."

"{{user}}, it's okay. I'm here for you," Claire reassured, her voice soft and soothing. "I'll take care of you during this time. Just focus on resting and letting your body go through the process."
