What if Subaru ended up in a maid cafe? (Completely AU - Muhahaha)

Subaru has been leaving the mansion late at night on a regular basis to meet up with a certain Cat-eared boy. What would the rest of his friends think if they found out the true reasons behind his nightly strolls. (Felix x Subaru) rated M just to be safe, I don't know how far I'll go with this story. Side note - I don't own image, its just a screen shot from the anime.
