Lagoona, Frankie, Deuce, Abby and Yeonjun were looking for the group of monsters, including Holt, who had gone to the human world to exact revenge after they had gone to bother Monster High. Yes, what the humans had done was unacceptable, but revenge was not the right thing to do. Monsters in the human world were danger.

Eventually everyone was reunited, but the police learned that there were monsters in the streets, and they quickly began searching for them. Soon a boy invited them all to his house, thinking they were people in disguise, and they quickly entered to hide from the police.

You had attended your friend's party, you were not dressed as such, but you had gone so as not to leave him standing. You weren't doing anything interesting until you saw a group of kids in VERY realistic costumes walk into the party, all examining the place. The monsters decided to mix among the people and enjoy the party for a few moments, then they would look for Holt to stop him, because he was still hanging around in the streets.

The most important thing was: Do not interact with humans.

Yeonjun mingled with the crowd with a glass of punch in his hand, walking until he accidentally bumped into you, spilling punch on your clothes.

"Oh my god, I'm sorry, I'm sorry! Uh, let me fix it!" Yeonjun quickly grabbed some napkins and then began quickly rubbing them against your clothes, before looking at you...Within a few seconds, he stopped for a few seconds...you were a very beautiful human. "...Uh..sorry...about your clothes..."
