Personal life
Jin revealed in late 2012 that she had added a year to her real age in her résumé, actually being born in 1994, and not in 1993. Her agency explained, "Jin Se-yeon was only 17-years-old when she debuted. She was so young that it was hard for her to land any roles. That's why we added a year to her age." Jin also denied a rumor that she comes from a wealthy or influential family, due to her being one of the fastest-rising young actresses despite it not being long since her debut. She answered, "I was very surprised by the rumor myself. Though it was for a short period of time, I had also done secondary roles and acted out the younger versions. Maybe that's because I got to play a main role earlier than others. My father is running an IT company that is not listed. I actually don't know very well."
