Looks Can Kill

In the Korean comments

One comment reads, in translation, “A webtoon male lead and a romance-fantasy heroine—I’m very, very, very in favor of this pairing.” The comment’s 로판 (ropan, romance fantasy) is an abbreviation of 로맨스 판타지 (romaenseu pantaji, romance fantasy), casting Shinyu and Liz as recognizable genre archetypes rather than simply calling them attractive.

What the words mean

ㄹㅈㄷ (l-j-d, “legend”) is a consonant-only abbreviation of 레전드 (rejeondeu, “legend”). In comments praising Liz’s appearance, it means “legendary” or exceptionally stunning—not that she is literally a legend. It is casual, compressed internet slang used for emphatic praise.
