I won't lie, I started this show because of exactly what you're thinking of: Hani.
Going into it, I had a few reviews and comments in mind so I wasn't expecting much. People called it "your typical romance drama", so why did even the very first episode feel like anything but that?
If the only thing you got from this was the incredibly awkward development of Nana and Danny's relationship, that's your business. What it caught my attention with, though, was the story of learning to accept yourself, your past and present mistakes and grow from them. Oh, and beautiful friendship, too. The show had it all: I laughed, I cried, I sympathized and all that jazz. It had its ups and downs but was enjoyable, nevertheless.
Wish to see more of them in the future!
