Twinkling Watermelon

In 2023, Eun Gyeol (Ryeoun) is a high school student who is passionate about music. During the day he is a model student... but at night he plays guitar in a band. But when he stumbles upon a strange and seductive music store, he goes back in time to 1995. There she comes face to face with her father Ha Yi Chan (Choi Hyun Wook), who is a high school student! Yi Chan thinks Eun Gyeol is crazy when Eun Gyeol calls him “dad”. What's worse, it seems that Yi Chan is in love with a cold cellist named Se Kyeong (Seol In Ah), instead of being in love with his future mother Cheong Ah (Shin Eun Soo). To try to fix things, Eun Gyeol joins a musical group led by her future father. But will this be enough to help Eun Gyeol reunite her future parents... and will she ever return to the 2020s?
