Honestly, there are much better dramas out there. I found the main characters to be particularly frustrating and the main male lead character to be absolutely immature (however, props to Lee Jong Suk tho because he did a great job). Besides that, the big age gap between the mains are not my cup of tea either as I only saw their chemistry in a brother-sister relationship. However, I really enjoyed seeing the side characters develop over the course of the entire drama and it honestly saved the show for me in my opinion.
