Is it the cast?
Nope. I like Choi Min Ho. Sure I know he is not the most talented actor out there. But he was fun in "To The Beautiful You" and his eye candy status covers a lot of flaws. Especially in a breezy role. Have not watched the leading lady (Park So Dam - Veteran)_ or 2nd lead (Kim Min Jae - Persevere Goo Ha Ra) much, but just judging from the trailers I have no complaints as yet.
Is it the plot?
No again. Sure they can say it is a realistic telling of life of twenty year olds in Korea, but I can't fail to take in account that we have a rich leading man, a poor leading lady, and a nice poor 2nd lead. It does not sound like they are trying to rewrite the genre.
So what is the problem?
The problem is that this drama is penned by the writers behind "Discover of Romance" and the "I Need Romance" chain of dramas. While I was able to tolerate "INR 3", the rest of their dramas made me want to chew nails. Often their characters are horrible people and their relationship decision making is downright toxic. Every time I try to give their shows another chance, I am burned.
