Byeon Woo Seok Saves Kim Hye Yoon

The beginning of episode 4 of Lovely Runner shows Im Sol (Kim Hye Yoon) waking up in a hospital in 2023. Someone found her in an unconscious state and brought her to the hospital. She then remembers what has happened to Ryu Sun Jae (Byeon Woo Seok). Thus, she rushes to his funeral with a heavy heart. The security does not let her go inside the funeral room, and she breaks down in tears.

Im Sol decides to return to where she first experienced time slip. She wants to return to the past in 2008 to save Sun Jae. But Sun Jae’s watch does not work, and she fails to time-travel this time. When she returns home, she gets a call from Sun Jae’s friend, Baek In Hyuk (Lee Seung Hyub). He tells her that Sun Jae wanted to apologize to her for some reason. But before he can reveal the reason, the call disconnects. Thereafter, when the clock strikes midnight, Sun Jae’s watch again starts to work, and with the help of the watch, Sol goes back to the past in 2008.

Lovely Runner episode 4 then displays that although Im Sol has returned, a lot has changed in the past, as it has been ten days already since she traveled back to the present. Now, she is Kim Tae Sung’s (Song Geon Hee) girlfriend, and Sun Jae knows about it. Her old self has even lashed out at Sun Jae for trying to talk to her. Thus, Sun Jae is now trying to maintain distance from her. No matter how much Sol tries to communicate with him and mend their relationship, it doesn’t work. Sun Jae refrains from doing so as he is heartbroken by Sol and Tae Sung’s relationship.

Meanwhile, Tae Sung keeps on expecting Sol to behave like his girlfriend. He has no idea that she is the future version of herself. Furthermore, Sol ends up celebrating Tae Sung’s birthday, making him feel special. It looks like Tae Sung’s feelings for Sol have started to grow even more.
