I felt the entire build up when nowhere. Maybe somebody got fill me in.

Mr Gu for some reason is an alcoholic without much explanation .

Mr Gu is an alcoholic yet extremely athletic.

If he was a top boss why did the chairman allow the other guy try and kill him? why not interfere? 

Nothing about his past is really explained  and just so many holes.

Yeom Mi Jung is pretty much an emo who makes pretty much no progress in trying to be liberated.

Yeom Chang Hee pretty much randomly breaks up with his girlfriend see's her in public and nothing.

Another girl likes him and he does nothing both times. He was just all over the place, breaking up

and playing the victim.

Yeom Ki Jung - is probably the thing that annoyed me the most ,they were building her up with

Jo Tae Hoon , they finally got together and they did a time skip straight away and their relationship

 went   nowhere. During episode 13 She and his 

daughter finally talked for a moment thinking its

 going somewhere and the next episode is a time

 skip and nothing changed.

All the side character's after the time skip were

 pretty much forgotten and not their.

One of the things i don't like about some south 

Korean show's are the time skips, it either drags

 the show out and you miss what happens in between or they try and cram everything in and it feels 

rushed

before the time skip it was 8/10 but the last 3

 episode's made the entire series for me waste of 

time. they shouldn't of done the time skip , they

 could of ended it with Yeom Ki Jung building a 

relationship with Jo Tae Hoon  and his family, Gu 

comes back etc.

Doesn't explain how long the time skip was

 6/10 obviously its a personally opinion 

time skips are realistic here personally 

This is not a romcom where you should expect something; something that has been your prejudice because of other works of dramas or movies. This was clearly a journey of persons with particular characteristics. People staying together in the end doesn't always guarantee a good ending. And if they didn't do time skip, then how they would have shown liberation?
