Lovely Runner

After Seon-jae's concert, Sol finds out that he's found dead. Full of confusion and despair, she wakes up and finds herself in 2008, where Seon-jae is still alive.

Sol is confused about the situation she's in and thinks she's already dead, but she realises that her mission is to protect Seon-jae at all costs.

As events unfold in surprising ways, Sol wonders if Sun-jae's fate is preordained and her efforts to change his future are doomed to fail.

Sol is back in 2023 and finds that some truths have been changed. She gets to return to the past again, where she finds herself dating Tae-sung, and Seon-jae feels confused and betrayed by her.

Sun-jae is able to save Sol in time, and In-hyuk asks Sun-jae to sing for his band in a contest, but Sol is upset when she sees him singing on stage.

Sol breaks up with Tae-sung and learns about Sun-jae's feelings for her by accident while listening to her MP3.
