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).
