손석구 눈빛 연기 미쳤다 진짜

I binge-watched 'A Killer Paradox' yesterday and Son Suk-ku's eye acting was so good ㅠㅠ Especially in the scenes where he clashes with Choi Woo-shik, the tension was through the roof. If you had to pick just one Best actor chemistry from dramas you watched this year, what would it be?
