I was looking forward to watching this drama from all the trailers and teasers I had seen plus it also staring Suzy who is one of my all time favorite idols so I was instantly drawn into it. The drama started off so strong with excellent character introductions and development, the characters felt real and relatable with each conversation and scene feeling natural. The development between the relationships felt perfectly timed and with roadblocks being resolved quickly. All of this was up until Episode 7, that was when the writing and the characters became a complete mess. Each decision the leads made felt like a slap to the face in everything that was established in the first six episodes. Everything the writers were building up to that point they just tossed into the garbage and forgot about it from there. In some instances, the characters felt completely different from the ones the drama started off with initially.

Open Ended endings when done correctly are a fantastic however this one was not done correctly, it was done so poor that it requires the viewer to go back and watch the drama or look up on the internet about what actually happened. Having invested time into these characters and their story only for it to end on the most flat open ended endings I have ever seen out of any media I have ever watched or played. To put it plainly, it was like buying a scratch off lottery ticket and instead of it saying "You Win or You Lose" it instead told you "You maybe won or You maybe lost". This drama's story required a defined and resolute ending to its story, this was not a science fiction drama that could have questions left unanswered nor some cop drama which left an investigation's potential culprit a mystery. I could have overlooked all of the mistakes and mess that was made during Episodes 7, 8, and 9 if the ending was not some vague nonsensical mess that required a re-watch of previous scenes or a web search to have it be resolved.

One of the best thing about the drama is the cast it had. Suzy knocked it out of the park with her performance as the titular character Doona. she played the role of the fallen out of grace idol that was a complete mess perfectly. Yang Se Jong as Won Jun was great as well, his problems of having to help Doona put the pieces of herself back together throughout their relationship and having to bare the burden of giving up everything for her felt very relatable. Ha Young as Jin Ju was a great secondary love interest that in my honest opinion, was the much better choice for Won Jun in all honestly. The rest of the supporting cast was great as well, they really did a great job in contributing to the story. One minor disappointing thing was that the drama never revealed the relationship of Doona and Won Jun to Won Jun's bestfriend Su Jin who was Doona's biggest fan. It was a missed opportunity, which the drama had several of those unfortunately.

The soundtrack itself was solid with it being an all around great OST, there isn't really any stand out tracks other than Ordinary Days which itself was performed by Suzy and Daylight by BIG Naughty. The cinematography was perfect, everything about the drama's production was high quality. Also excellent job in being able to show the emotions of the characters through camera shot styles, its rare seeing a drama being able to do that.

All around, I wish this drama didn't throw away all the great work in started with in the first six episodes. Had they continued with that pace, this drama had the potentials to be one of the greatest drama's of all time but unfortunately the drama self sabotaged itself leaving myself and many more viewers disappointed and unfulfilled.
