Sojin used to work as an interest clerk in a bank. She was in charge of keeping track of loans and interest owed to the bank or to the customer. Sojin liked to give little pieces of advice at the side, expressing her genuine concern for the customer's welfare. When a bank robber charged in one day and declared a hold-up, she was unfortunately made his hostage. Sojin was beyond terrified - then again, who wouldn't be? A clumsy mistake (on both their parts) led to a bullet in Sojin's head.

Sojin deems it unfair that the man just took away her life with a pull of a trigger. She decided to undergo rebirth and come back as an even better Sojin - one who can and will accomplish everything she has wanted to do and one who can fix her mistakes from the past life. Sojin works as a radio DJ now, interviewing guests and playing music for people's enjoyment. Her ability to talk to people helps her carry out her job well.   

Sojin is naturally a bright and bubbly girl. She loves to interact with people; hence, her career interests. Sojin is also very sensible when it comes to life matters and is known as the advice-giver among her friends. She can be extremely clumsy at some points though, which may sometimes lead to embarrassing moments (never mind, they make good stories anyway).
