The making of a music video for Yurigooseul(Glass Beads), a debut song of a newly debuted girl group,
Yeojachingoo(Girlfriend), is released. It has gone viral in online communities since it is somewhat scary
to watch the members of the girl group bow to the staffs in the studio.

Netizens who saw the pictures reacted by saying, "Powerful group bowing",
"their hair is so long that it can touch the floor", "their hair reminds me of a unmarried Korean ghost lol" and so on.
