Okay so I was having a terrible day and my art was doing worse. Sorry. Juri and Osamu from Salva Nos. They're top-notch surgeons, though Juri is better at the technical aspects of surgery and has a much better bedside manner, and Osamu is much better at biochemistry and pathology. Also, at some point they struck up a friendship under Kurata's watch and started supporting each other and snarking behind Kurata's back (and Osamu's the only one with the gumption to snark to Kurata's face).
They're not actually a couple, though. Osamu is married and Juri doesn't want anyone right now.
