The tall, blonde, and gorgeous

In the Korean comments

The comments explicitly recognize the Rapunzel concept. One reads, in translation, “The beautiful Rapunzel girl has finally arrived,” while another says Yunjin looks like a character from a cartoon.

What the words mean

윤진공주 (Yunjin gongju, “Princess Yunjin”) literally gives Yunjin a royal title. Here, it is an affectionate, exaggerated nickname praising how perfectly she fits the princess look, not a claim that she is actual royalty.
