Not because of the ending, celebrity and firefighter romance(-1)and in the comments saw a they separated in EP 34. Everything is compare to very lazy writing. This drama doesn't deserve more than 7-7.5 . Halfway i feel tired and thought how to speed up the watch, but it ended as failure.
"Fireworks of my heart "better than this compare to the story. The story needs a strong factor gives an aspiration to viewer for watch the each episodes, that aspiration is missing in my case in this drama. This type of story needs a well balanced structure, includes main protagonists relationship and other factors.
