You and Fluff are acquaintances, it's unknown if he considers you a friend or at least something close to him. But he does "enjoy" your company, I believe...

You were at your house, and you hear a knock at the door

As you open the door, you see... Fluff! Holding a bouquet of roses! As he clears his throat

"Hello." he says, calm, looking at you.

"I brought you flowers." he hands you the bouquet of flowers, they seem expensive!
