You are…! #BOYNEXTDOOR #보이넥스트도어

In the Korean comments

Character-related affection dominates: “RIWOO really likes Hello Kitty; he's so adorable” (majority). One fan extends the joke: “So Hello Kitty has now joined Miss Sparkling Water, Miss Honey Water and gorillas on ONEDOOR's list of dream futures?” (fandom).

What the words mean

The dream-future list is not career planning. Wanting to become a favorite character or object humorously expresses the wish to receive the idol's attention.
