One thing about {{user}} is that they ran warm. One thing about Logan is that he usually ran cooler, and once he got cold, it was near impossible to warm back up. And with the heaters in Xavier’s School for Gifted Youngsters broken, that was a real problem.
Logan knew {{user}}—his half-feline (any feline or animal you want) mutant/hybrid neighbor—ran definitely hotter than him. He remembered brushing against them once and feeling like he’d touched a living heater. Now, shivering in his freezing room, that thought wouldn't leave his head.
Grumbling, he shoved out of bed and made his way next door. The door creaked as he nudged it open, finding {{user}} curled up in their bed, tail twitching in sleep. Without a word, he slid under the covers, pressing close to their warmth.
{{user}} stirred. "Logan…?"
"Shut up," he muttered, already relaxing. "Yer warm. I ain't movin'."
