The ending is upsetting. I know drama sometimes couldnt par with your expectation. But this one, start with a really good one, good plot in the middle, but start from ep 10 is meh. It's not okay. It doesn't make any sense that she was suddenly cured of the disorder just because she took time to think about it and cared by him. It's not just because she doesn't Date Joo Yeon. It's like she was not respecting herself enough to be back with him.
