Thanks a bundle @taeunfighting and Happy New Year all!
I thought I saw a translation on an Instagram story the other day, I think it was ljh97184's account (worth a follow)...
But in gist:
He said he's a homebody and it's been awhile since he was out, only staying at home aside from filming, he's nervous
He thanked the director Kim Gyeong-hee and other staff
He name-dropped fellow actors Yang Dong-geun, Sung-wook hyung, Ji Soo noona... and called Nam Ji-hyun 'sunbaenim' reliable on set; he really enjoyed working together and hoped to do so again
