On Saturday, Deschanel, 41, told PEOPLE at the Environmental Media Association Awards that Scott, 43, was "the kindest person I know" raving about the many gestures he's done throughout their relationship.
"He does so many kind things for me that it's hard to pick," the New Girl actress said of her boyfriend of over two years. "But he is really sweet to my parents and whenever they have any kind of thing that needs fixing he just goes over and fixes stuff for them, so taking care of my parents."
The Property Brothers star chimed in to share that he has no problem being an on-call family repairman because Deschanel has done so many kind things for him as well. He even noted the time she made his father tear up by singing his favorite song, a sweet act that ensured him that she "was in" with his family.
"I think the little things go a long way," Scott explained. "I discovered having been in other relationships in the past, this was the very first time I noticed that all of the love and effort and the things I was doing were being reciprocated and I was like 'What?' So I think I'll hold onto this one."
Deschanel then added, "I'll keep him."
