Ki Sun Gyeom is a professional sprinter who was forced to quit due to legal issues. He crosses paths with a film translator Mi Joo briefly works as his translator. Through time and communications, their mutual interest pushes them passed their boundaries

Run On is a drama that is not baiting for my attention as it has a very subdued vibe, but I enjoyed it very much. Not many external conflicts going on, it’s a character-driven show where the main and supporting characters’ plot are very much intertwined. I like Sun Gyeom's quirky and very kind-hearted personality, and I’m enjoying how he interacts with people around him. I appreciate how he’s very blunt to anyone. The romance is also toned-down but wholesome. Sun Gyeom and Mi Joo’s chemistry is a lot softer than most Kdramas, it feels very realistic and heartfelt. The secondary romance of Dan Ah and Young Hwa I wasn’t really paying attention for their plot but they have great emotional moments.

Another highlights for me is the playful, quiet, subdued humor in the show, it was pretty clever and sharp, those moments were few and precious. For example, when Seon Gyeom wakes up in the morning and he's getting ready for his morning run as it has been his routine for years. One morning, when he's getting ready, he stops halfway and realizes that he doesn't have a reason to run anymore, so he turns around, throws off his jacket, kicks off his shoes, and rolls back into bed. I found that’s absolutely hilarious! This is just a small no-dialogue moment but so memorable. Also, I am happy to see a positive representations of LGBTQ characters here, as they are seen as part of society. The only nitpick I want to mention is that there’s something missing throughout my watching experience… Although the character development of the main lead was great, it felt slightly boring. Overall, I am happy to have known these characters.
