Looks Can Kill (eyebeam ver.)

In the Korean comments

One top comment reads, in translation, “Because Jang Wonyoung is tall, the height difference when she stands beside Joo Woo-jae is just the kind that makes your heart flutter.” Another casts them as drama archetypes: “It feels like a sparkling, popular heroine together with a grumbling, introverted male lead.” A separate commenter was surprised that Joo Woo-jae dances better than expected.

What the words mean

안꿀리네 (an kkulline, “doesn’t fall short”) can literally suggest not being cowed or pushed back. Here, the commenter is saying Joo Woo-jae holds his own visually even beside Wonyoung; it is casual, emphatic praise.
