Hajae Kim, a 28-year-old cram school teacher, realizes that he has returned to the day he was taking the college
entrance exam. Everything started with a phone call. He calls his friend, who he had a crush on for ten years.
He was invited to his friend Chahyeok Choi’s wedding. Later he gets drunk and calls him. “I wish you never met
Baekna….” He wished that the man he loves never met his fiancé. As if his wish had been answered, Hajae travels
back in time to the point where the couple had not met yet. Now he has to think and act fast, to put an end to his
long and painful crush.
