I saw this in a FB group... (Patreon)

In the description of the photo teaser of Haseul says "a folded paper moon".

A paper needs to be folded 42 times to reach the moon and remember that digipedi had uploaded a photo with two people dressed as astronauts.

It should also be noted that the episode #42 of LOONATV is when Haseul arrived in Iceland.

BUT more importantly SHE LOOKS SO GODDAMN BEAUTIFUL WITH THAT HAIR
