I am absolutely livid at how this show ended. This was one of the best love stories I've seen in a kdrama in ages. I haven't felt so captured by the two lead's emotions and the story as I did in Twenty-Five-Twenty-One and it hurt when you find out that they didn't end up together. The actors and story did such a good job in making the viewer believe in love and then they rip it out from underneath you. I've set the rewatch value at such a low rating because I don't think I can put myself through that kind of pain again. Like I avoid these types of painful situations in my own life for a REASON. I'M TOO WEAK AND WILL NEED TIME TO RECOVER AFTER WATCHING THIS.
