This drama is a bit old, so some of the characters have very old fashioned way of thinking, but I have to admit that it's a bit forward in certain aspects.
The things I liked most were the relationship between kids and uncles (especially Pa Rang and Kang Ha, they share a very cute bond and I have to say Pa Rang is the very hero of the whole drama even tho at the beginning was a bit annoying - I swear later he grows on you) and how the female lead became from a superficial useless girl to a very cool woman who never lost her cool (there was a moment in the middle, when Kang Ha almost married that other girl, but for the rest she was okay). Usually in those kind of old drama the female lead's traits never changes but they're even seen as an attractive point for almost all the guys that will appear during the story. She's not nosy, loud, she doesn't do things for her loved ones sake and , when she decided to change her life, she stayed faithful to her new attitude. Just don't judge her from the first episode.

The chemistry between the main leads is natural, especially when they argue but there's a lot of time stole by that useless second leads subplots. And this is what I was thinking talking about "old fashioned" the second leads are more clingy than a gum on your hair!! Both Jae Young and Joon Ha had no consistent reasons for their attachment to the main leads and they just don't know when to give up (BUT they magically do it near the end, like that.)...she had to marry him because she decided so, there's no love involved, she just thought something like "we're beautiful and successful so we are a great pair"...how pathetic would that be? Add to this the fact that she went around slapping and yelling at everyone just to vent her frustration and we have the most annoying character ever imagined. I think they should've added a serious reason to make her fall in love with him just to begin with ...I mean she even threatened him to reveal the big secret to the brother (the "big" secret of them being step brother...and he knew already!! All that episodes wasted like that). And for Joon Ha I kinda liked him at the beginning even if he seemed like a weak character, but I don't understand at all his changing obsession between the two girls so fast...he first was madly in love with JY and for her sake he started trying to steal Pal Gang from his bro but he fell for her like that, in two seconds he didn't remember anything good about JY (quote). And that girl that won't cry thing, I don't even understood how good of a reason to fell for someone would be. She was a spoiled brat from the beginning.
The worst of the worst was that verbal duel between the brothers "I can't steal her like I did with our mother" "for my bro's sake I can give up her"....she doesn't get to decide whom she like?? Why I had this feeling her opinion on this matter was so unimportant that she wasn't even asked about it?
*I really need to insert that Aladdin's gif where Jasmine scolds everyone for playing with her future like she's some sort of prize*

The nephew was cute with the kids but really he was an unimportant character...he's here just to have another contestant for Pal Gang's hand but he didn't even stood a chance so meh. I wish he would've given up her before and started being a cheerful character with no romance implementation... (You are in dramaland when a whole family just go nuts for the very same plain looking girl lol)

But beside clingy characters and bipolarism it was entertaining for at least the three quarter of it - in some parts I even thought "wow this is very good" (when it was more focused on the family struggle and the children), so I suggest to give it a shot if you like those improvised family drama when leads become surrogate of dead parents and slice of life ones.
Also I loved the fact that the kids and the girl had all color names! I learned something in Korean!
Ps. Some of the characters has different hairstyles than the posters o.o
