Operation: True Love

Su-ae Shim knows firsthand the difficulties of dating someone who neglects you. She has been in a relationship with her disinterested boyfriend, Minu Kang, for many years, but still envies her charming stepsister, Ra-im. However, a bizarre twist occurs in Su-ae's life when she discovers a talking flip phone, named Jellypop, in her locker. Jellypop becomes an outspoken critic of Su-ae's romantic situation, especially as she distances herself from Minu and starts to spend time with his friend, Eunhyeok. As doubts grow about the potential connection between Minu and Ra-im, Su-ae may require the intervention of a higher power to navigate the tumultuous world of teenage relationships.
