Loved this drama! I spent 2 days binge watching it because it was that good. I loved Sakura! She was strong willed and smart, and she reminds me of Hotaru. Though sometimes, I hated her hair so much! She takes the phrase "messy bun" to a whole new level haha.
I don't know why so many people disliked this drama though. To me, it was expected that she'd end up with Hiroto due to the age gap thing being the central plot line. I agree though that the writers included too much screen time between Sakura and Tachibana though. Because of this, it mislead the viewers.
