Yes, it is the hottest topics every K-drama fans whom had or hadn't even watched been talking about. Yeah, I know SG is a bit slow on this.... very laid back.... they will only talk about it when the news is already frozen in other part of the world.... Thus I have watched the show thru online stream before it's available here. The DVD store dunn even have a single clue on what it is..... They associated it with Air City instead.....
The On Air is sort of acronym of The One Sided Love Affair....Unlike other typical K drama, this show has a refreshing topic and exciting casts with caliber. It is also not as draggy and do have less flashback scene.
Beginning of stories it kind of rekindled the relationship around the main 4 casts which kind of complex indeed it's very simple. Sort of misunderstanding and jealous w/ each other. Stories are predictable along the way.....
I like Kim Ha Neul performance as Oh Seung Ah in the show, she was great in her acting and her haughty look and arrogant yet lonely character charms viewers' heart...... In ep 6, you won't expect that Oh Seung Ah as an arrogant and cool celebrity would be a terrible singer and she sang off key and act crazy in K-session.... it's just hillarious.....
My fave scene are all Kim Ha Neul's appearance on the scene and her relationship w/ Jang Ki Joon. 
It is just fantastic to watch both of them whom loving each other yet hold to express their feelings towards each other....
Another must not miss scenes are the scene b/w Oh Seung Ah and scriptwrite Seo Yoon Ah. Their arguing conversation are just thrilling to watch.....
If you watch the show, you might consider the OST where 4 of the main casts also contributed a song in the disc. such a great marketing idea in making money... split the album into two instead of just release one with the hype of the show going through...
