The first half of this worked quite well, nothing new in the plot but the characters were at least interesting. I liked Sam Soon, she had enough feistiness to make her interesting even though she still fell into the usual drama cliches. The fact she was plump (though still gorgeous!) was a really refreshing change. The initial squabbling between her and Jin Heon had chemistry, humour and timing, lifting the show above the relatively ordinary plot.

After a while though, the repetitive unpleasantness, wrist grabbing, shouting, arguing, cheating and so on just got wearing. The initial humour was transferred to other characters leaving the main leads looking a bit pathetic. It's really hard to care about the relationships of people you neither like nor respect.
By the time I dropped it I'd really had enough of Jin Heon, what a complete twat he turned out to be. I don't mind a lead who starts out as a pathetic man-child but grows and changes into something more...adult? Likeable? as the show progresses. Unfortunately JH just got worse and so by the time he at last started to come round a little bit I no longer cared. Which left Sam Soon with her repeated 'he's my last chance' as the only visible reason for sticking with him seem even more sad. Well he is rich I suppose...

The music has some gems thrown in to the mix and made me smile on a couple of occasions

Sam Soon I wish you could've found a nice guy or at least one that you could trust.
