Honestly, this show would have gotten a 9 star review, if things didn't take a weird shift when the characters got into college.

The story first focused on both the FL and ML, until the second part where the FL's storyline was overshadowed. It wasn't like she wasn't there however the balance between them was thrown off. After part one, the main focus should have been the aftermath of what happened in highschool. However, the subject of focus wasn't correct and was executed in a very bad way. Which is a shame.

Since this story is an adaptation, I cannot say what had changed except from what I've read of the novel's description where the ML's financial situation isn't the same. Whether they did more changes beyond that or they written something different with small references to the original work, I'm not sure. Either way, the change in the story is a bit too big to be overlooked, even with a great cast.
