듯이 보다

look at someone like X

-듯이 means 'as if, the way one would', and it characterises the look someone is giving: 왜 이렇게 나를 벌레 보듯이 보냐? 'why look at me like I'm an insect?', 캠든이를 되게 아기 보듯이 보기 때문에 'because she looks at him the way you look at a baby'. It also describes the manner of watching something: 스쳐 지나가듯이 봐가지고 'I only caught it in passing', 복습하듯이 보시는 걸 추천드리고요 'I'd suggest watching it as a review'.
