Are you bored on your walk?

In the Korean comments

One commenter writes, in translation, “I thought the passerby was a New Yorker, but it was the other members,” specifically spotting blond Stella and Juun in sunglasses. Another points to the moment Jiwoo appears close to laughing after seeing Ye-on, giving viewers two background details to watch for.

What the words mean

북부대공 (bukbudaegong, “grand duke of the north”) is a romance-fantasy archetype: someone icy and aloof who softens around one special person. A comment affectionately casts Jiwoo in that role, saying even a cold “northern duke” smiles at the “baby.” 웃참 실패 (utcham silpae, “failed to hold back laughter”) likewise means that someone’s serious expression cracked; here it is playful shorthand for Jiwoo being unable to maintain hers around Ye-on.
