Unintentional Love Story was a very lovely story to watch unfold.

The music was otherworldly in how good it was at expressing the emotion of the scenes.
The acting by the leads Cha Seo Won and Gongchan was honestly breath taking. Whether it was new love, heartbreak, betrayal, or just not feeling the vibe they were able to deliver it in a very profound and nuanced way.
The supporting actors of Han Do Woo and Won Tae Min were also entertaining and quirky adding a breath of comedy.

My biggest problem with this drama was it did not give itself an adequate number of episodes to properly pace out its complex narrative. This show would have been far better served as a 12 episode series, allowing for a full rounding off and complete deep dive of all its moving parts.
The lead relationship when depicted as functioning needed more action time before things went south in my opinion.
And the supporting relationship never was given the time to fully come to fruition on screen leaving one to wonder what is going to happen next.

Other than that I would recommend this show to anyone who enjoys a good drama. It has a lot of heavy elements making it less of an easy watch, but nothing that detracts from its enjoyment. Great acting, great emotion, interesting premise, and lovely music.

P.S. Be prepared for a lot of pausing because the close captions move very fast.
