Lupin is such a fun, and alluring name! It feels super witchy and overall the vibe of names like Beatrix and Amethyst ☺️. My friend's name is Lupin, but I always call them lulu. Unisex and awesome choice, I would totally use it! 💐 by the way, the meaning is super cool as well! Pertaining to the wolf is just gorgeous. 🤍.
