*Mini rant with spoilers ahead*

I went into this expecting a healing/fluffy drama but was surprised by the mystery. It was unexpected and out of place. The story started as a light drama about airport employees. It sets up a romance between a woman plagued with bad luck and a mysterious man. The drama and romance was realistic and sweet. The side characters' storylines were my favorite parts. The acting was great too.

This drama suffered from one terrible plot point. Why did he have this bionic arm that gave him super strength? The drama could have been interesting without it. He could have just been disabled without the Winter Soldier superpowers. The mystery could have been the same, and the drama's tone would've been more consistent. I've rewatched this a few times and I always skip this plotline.

It's a good drama if you skip the sci-fi stuff which is why I rated this so high.
