Lovely Runner is based on a web novel titled Tomorrow's Best. I personally read the manhwa while the series is on-going I can see that they made some drastic changes from the story. The manhwa is less complicated compared to the series, but I like the changes they made on the story it actually adds up to the uniqueness of the drama. What I really love about Lovely Runner is that it never fails to make me laugh every single time. I like the balance of the show's theme it's a combination of comedy, romance, thriller, mystery and drama.

Aside from this the cast did so well that their acting felt so natural, all of them deserves to be recognised for their versatility and they played an integral part on the story. The villain did his job so well that I almost wanted to be included on the story just to choke this guy. I would also like to point out how I love Baek In Hyuk's character, he's the best wing man ever. Ryu Sun Jae would've been a forever simp without the help of this guy. I am looking forward to Lee Seung Hyub's future drama where he'll be the leading man, I bet he's gonna be a great male lead since he already showed his exceptional talent in Lovely Runner.

Kim Tae Sung's character is also my favorite from this drama, his character development is the most noticeable among them all. He unknowingly fulfilled his promise to Im Sol that he'll protect Sun Jae in the future. It's just kinda sad that we didn't get to see a glimpse of his back story.
