One day, a secret man steals the house of the world-famous Stray Kids group. When the Stray Kids group opens the door, they see a man in front of them. The man is holding a girl with purple hair and a very cute dress, but she is unconscious. Without saying anything, the man gives the girl to Bangcha and runs away. The girl has a note on her that says "This girl is special, take care of her" and Bangchan takes the girl in and waits for the girl to wake up.
