other folks will reply with what affectionate nickname their character would call yours if they were significant others...because now, they are!
pet names can be a simple riff on/shortening of someone's name, cute, stupid, sexy (babe, etc), serious (my sun and stars), time period appropriate (dollface), or just plain weird. sky's the limit.
from that one(ish) word prompt, threads spring eternal. shippy, smutty, adventure-filled, angsty, cracky, whatever. go with it!
