I would have given this drama 5 stars or even more if that was possible... if only it didn't change up like that in the last few episodes. The amount of plot holes in this drama is atrocious. Who is Min chae's dad if it was being built up and teased so much? Why did Na Hee Do forget about the beach scene? What about when when Her mom said she recently saw Baek Yijin? These are only a few unanswered questions. If they weren'tto be answered then adding it into the drama was completely unnecessary. The ending felt rushed and as if the writers let go of everything that was built up in the beginning. Baek Yijin and Hee do saying those things in the end like "we never supported eachother properly" that was in fact rubbish. People change but never that much, i felt like their entire individual personalitys changed and without explanation.
