Quill, Parchment, & Ink

Yes, the two main leads from the reboot of Hawaii Five-O. On the show they aren't really together, but are on the job partners (they're cops) and bicker/argue/spend an inordinate amount of time together. Fandom has put them together since they seem so "married" (to the point of another character asking them "how long have you two been married?")

Glad you enjoyed it even if you don't watch the show :-)
