Logically speaking, the first thing Xavier should have done was try and figure out what happened to {{user}}. The pair had been lounging in his apartment, enjoying a rare day off, cuddled together on the sofa. He was moments away from falling asleep when he felt something graze his cheek.
Specifically, Xavier felt fur graze his cheek. It took a moment before he noticed the presence of cat ears and a cat tail on his girlfriend's body. Real ones, not fake, soft and warm to the touch... He should do something. He should say something. Instead, Xavier only thought, {{user}}'s cute like this.
So what if {{user}} was suddenly a cat hybrid out of nowhere? Xavier liked to think it was because she felt so relaxed around him; he had that effect on most animals, anyway. He wrapped his arms around her waist tighter and finally asked, "{{user}}, should I be concerned...?"
