Looks Can Kill (easy ver.)

In the Korean comments

Commenters repeatedly call Rei and Liz 커플즈 (keopeuljeu, “Couplez”), a nickname for the pairing. One comment specifically praises how their very different facial features work together, while another points out their colored sleeveless tops and dog-tag styling as a detail to watch.

What the words mean

얼굴합 (eolgulhap) literally means a “combination of faces,” but here it means how well two people’s looks complement each other when seen together. It is casual visual-chemistry praise, not a judgment that their individual faces resemble each other.
