First of I want to emphasize that this isn't a romantic comedy and that the description of the drama doesn't suit the drama!!
It's not super duper deep but it's topic is quite serious and revolves a lot around self love. I watched all 10 episodes after another and I did like how the story developed. However it dragged a little from Episode 5 to 7. It got a little bit boring during this part but they added new stuff from 7 which made it almost feel like a new drama.
Character wise the development seemed a little hasty towards the end, some characters didn't make sense a lot or their sudden change of feelings towards each other. Some relationships were also not really explained or well more likely their background. I feel like they could've shorten the first part of the drama, add maybe some funny elements. Because believe me, I didn't laugh a single time, but cried eventually. I think depending on what you usually watch this might be heavy. Like don't get me wrong it's not traumatizing or anything but I feel like it can trigger some people. What stuck with me the most is the sentence "only unrequited love can last forever". Also from this sentence you can see the overall tone of the drama which leans more towards sadness and grief more than happiness.
I was intentionally looking for a lightweight cheesy rom com which this is not even close...but despite it wasn't what I was looking for nor what the poster and plot summary makes it seem like, I actually enjoyed watching it and would recommend it to people.
