The concept is so simple. What makes it masterpiece is the dialog is so well written, and some of them are mindblowing. The dialog often not to be made "scripted" but rather natural.
The plot itself is rather predictable. So if you are looking for some plot twists, there aren't much. The strength of the movie is the life lessons. So many of it that we could relate to our life, especially when you're in your 20s-30s. For what it is, it's pretty fair and not edgy at all.
I personally enjoys plot-based movies. But this one caught my interest even more every second of it. I watched the first movie with family on the cinema (I wasn't sure why I would watch a drama on cinema but yes, with family thing), it was amazing and so well written. This one is no inferior then the first movie.
Very recommended to watch, especially those who are still working on their love life but parents are tougher than rocks, stricter than a General to their soldiers.
