Min Yoo Jung is a 25-year-old woman who dreams of becoming a successful pop musician. But her musical dreams are a long way from coming true – and she spends her evenings busking on the streets. Life takes a turn for the weird when Park Yeon, a talented musician from the past is transported from the Joseon Dynasty (1392-1910) to the present day, where he meets Min Yoo Jung and indicates he is ready to help her on her musical quest. However, he is not the only time-traveling visitor to drop in on her: A gifted vocalist by the name of Lee Won also travels from the distant past and makes her acquaintance. And things get even more complicated when Jung Do Young – an entertainment industry professional – uses her own powers to connect with the past to learn of Park Yeon’s secrets… Adapted from the webtoon "It's Thorny" (가시리잇고) by Park Sun Jae (박선재) and Ra Hee (라희).
