Slight Spoiler at the end.
So Min and Hae In are both actors that I appreciate and are enough of a draw that I will attempt any of their shows.
I actually made it quite far into this one before stalling on episode 10. The main reason? I didn't really like any of them.

Seok Ryu probably ended up with at least my sympathy but Seung Hyo got me to the swearing at the screen stage.
Indeed by episode 10 I was FFing past everything but So Min - the Ajummas? the sets of parents? the architect staff, the second couple, the son all got a big fat 'who cares' from me. They were all so seen it before one dimensional fillers that I didn't need to pay attention to understand their roles. The teapot lady and the ex were equally meh.

the secondary couple were just so squeaky and twee with no jeopardy that I didn't care about them at all and why was she so obsessed with the kid?

The chemistry between the leads was also lacking which really put the nail in it for me, very disappointing. I got to episode 10 and and didn't get any feeling of love from them.

I found the music terribly wishy washy and 'nice' and turned the sound off on a couple of occasions when it started to bug me.

I may go back and finish it but I may not. Looking at the directors shows I get the feeling his style isn't for me only Oh My Ghost stands out as above average.

***spoiler if you go through a traumatic experience and someone you care about finds out after the fact
Making it about you in a non judgemental way = yay nice person
Making it about themselves and their feelings and attacking you for not considering their feelings = bunch of twats.
