Beware, it’s going to be long and with spoilers!

So my test-retest reliable but I liked just a bit more the Kdrama so I gave another half point. Below will be my comparison between this version and the Cdrama.

The cons: They didn’t spend much time around their younger days and I loved it much more than the modern ones. I understand that the Cdrama was much longer but IMO they lost all the beauty of how they became a one big family. In the Kdrama they suddenly started sort of living together, and without the prior knowledge I might’ve been confused.
Their modern days wasn’t done perfectly either. It was fun watching them going between the apartments in the Cdrama and practically living all together again, but here it felt less like that, and they missed the whole thing of how they became neighbors again at the first place !
Another problem is the familiar faces of actors who are usually doing villain roles and suddenly you got to believe they’re the sweetest dads in the world. So I’m sorry but I liked the dad there more. And the Mom was much more savage here. It was painful to watch her scenes.

The pros: Real life age of actors! Seven was older than the guys, especially ML and it showed. I’m happy In Yeop was older, so I could’ve felt the chemistry more.
Also I liked that unlike the Cdrama where Seven was the glue between them, here it felt like In Hyup was the one. So he really felt like the protective older brother. He has done a terrific job.
Her friend was much integral part of the story and it was interesting they left her with the same character as she grew up and didn’t make her go against her mom like in the Cdrama. It showed much more what a sensitive and beautiful on the inside woman she is. It emphasized the growth of the 2ML (who, as he should, didn’t want the FL, even for an instance -unlike the Cdrama).
