Kim Himchan has never been spoiled considering he didn't have a good childhood, he was raised by a single mom since their father had drug abuse problems and went M.I,A when he was 7 years old, and his mother was pregnant with his younger sister. 

Gracie Barron has never known what it feels like to be in the lower class, all her life she had been wealthy since her father was a successful buisness man with multiple companies all around the world. She has no siblings so she gets basically everything she wants, she's spoiled but she's still a good person. Her friends aren't as wealthy as she is and that's how she liked it, in her opinion rich friends were boring and snobby

There's a party going on and Gracie's best friend is the host and Gracie is on the V.I.P list. Himchan is also invited on behalf that he will probably provide the majority of entertainment since he was an amazing singer. 

While at the party the two meet, and the only thing they have to remember each other is picture they took off a drunken request from Gracie.
