-Star Museum(SM) Sports Company-
SM Sports is a specialized company who develops the unseen potential of a sports person&groom them into outstanding atheletes.
However, rumours were said that this company treated their atheletes badly, by not giving them their deserved breaks, make them train long hours everyday etc.
These were rumours, they were never once being testified as the truth because none of the atheletes complained about their training schedules.
Dont know if the atheletes were threatened,blackmailed or there's simply no such thing going on in the company but just rumours spreaded by jealous companies who cant stand the huge success of SM Sports.

-Jessica Jung Sooyeon-
Only daughter of SM Sports CEO.
Hearing the word 'ONLY' sounds like Jessica's a precious little princess to her father right?
But sorry, nope the truth is otherwise.
Jessica grew up in the huge mansion owned by her father but only sees her father in the huge mansion maybe once or twice per year?
Due to a reason years ago, Jessica's father never once cared about her but just left her aside at home only to give her unlimited amount of money to do whatever she like.
Jessica also felt that whenever her father sees her, he would show her a disgusted look, as if he hated her daughter so much.
Sometimes it made Jessica wonder why would her father even brought her to this world if he hated her so much.
Jessica's mother died when Jessica was 5 years old due to an accident that was brought onto them due to the riches of their family.

-Kwon Yuri-
An orphan without any amazing social status or family background.
The truth is, Yuri never knew about her family background or who her parents were.
She was told to be found at the doorstep of the orphanage she grew up in.
And her parents never once came&look for her so she took it as the fact that her parents were dead.
At around the age of 7, Yuri were found by Jessica's father at a swimming pool.
Jessica's father saw the potential that Yuri had when she was swimming, her amazing speed&the looked so perfect despite Yuri's young age.
So Jessica's father took Yuri in&trained her, gave her education&lodging.
Yuri was actually a really smart girl, she swims well&her studies were great.
At the age of 18, Yuri got into Harvard Medical School in United Kingdom on a scholarship.
Mr Jung had to only pay for Yuri's expenses but on the condition that Yuri becomes a full time swimmer at his company,
take part in competitions to make his company proud.
