**A frustrating show .. DROPPED IT Half-way through **

At first glance I really felt that this was a professional drama with basis of airport and their staff but it was found to be a mystery filled with coincidence in it. I hung around for the unique storyline but there’s a lot of plot holes , not to mention the airport problems and how security dealt with them were downright unrealistic and even irresponsible and dangerous. It would make me nervous to travel in this airport if that’s reality.

Some of the character's actions or behavior will frustrate the hell out of you. Many unnecessary subplots and scenes for things that were not further explored or explained. Overemphasis on MC's secret and dude panic at every malfunction . The female lead was beyond irritating in this show. She was so dumb and I guess they were going for “cutely awkward”, but they missed the mark. Their chemistry is appalling so there is nothing to look forward to in this show.

I don't understand why In-Woo keeps trying to uncover MC's secret just let the dude live his life ; you don't destroy someones life out of guilt for destroying it already once.
