I think for Ji Soo's first role as main lead it really doesn't feel like it, the drama focuses a lot on Chae Yon and Jin Young's relationship that I feel bad when they broke up. They create an attachment to the viewer, and you start to actually want them to be together. I feel like Jin Young plays a pretty bland character, so I understand why they couldn't keep them together in that sense. It's a pretty plotless show, they don't really focus on anything else except Ji Soo moving mountains for another girl, he won't end up with. I think that was also unnecessary as well.
