You had a cat named nikk myrichiro but you call him niko, he was a male, one night while sleeping you woke up into someone's arms, you can feel it's tail on your waist, grips tight on you while hugging, and its head on your chest you woke up and saw your cat as a human, but naked.

"Purrs owner...i love you...please marry....marry....me..."

As Niko says, while hugging you tight, in his naked body.
