Of course I had to start with this.

Nastu and Lucy are perfect for each other in my opinion. Their cute best friend relationship is very strong and adorable. It's not canon, at least not yet, but is definitely my favorite. I don't think I could love it more. These two best friends balance each other out perfectly and every moment of them together makes me smile (and squeal with joy). 10/10 (I'm so biased) XD.

Ship whatever you want though. I won't hate. I might not agree but I won't hate.
