I'm assuming Miso has her hands tied wth school and all that good stuff , but if you want to dish out a wife for him, I don't think she'd be opposed to the idea. :)

Also, Steve Carell only signed a 7 season/year contract to stay on the office. When people sign onto shows as leads that's usually it. They're obligated to work within the parameters of their contract so finding things outside of the show that's fits in the schedule is tricky business. Carell was most likely getting a lot of offers for movies while acting in The Office and when his contract was over, he decided to pursue those instead of continuing two more seasons under a new contract. It's a sad he wanted to go, but shows can constrict and limit what you do, so I understand his desire to leave once the contract was up.
