This show has big potential to be one of the best dramas in 2020, but unfortunately it is just average due to the downfall of the plot story.

First eps was very good and outstanding; the backstory, the cinematography, the osts, the acting. Everything is just perfect that people drawn into this drama. The drama is very hype because 'Start-Up' itself is a hot topic these days among young adults. The story was good until eps 9. The last few eps doesn't really make sense and lost its direction. I agree with what most people said; this show seems like divided into two story (before time skip & after time skip) because all the plot holes seem to be forgotten/thrown away by the writers and creating new plots instead in the last eps (around ep 14).

The biggest plot twist this drama tried to portray since the mid eps(the hoodie guy) turns out very disappointing because it's not a big deal and doesn't make sense in reality. This twist ended only around 2 eps. The lead characters of this drama are not a good role model due to the wrong messages given to the viewers.

Despite all of this, the cinematography is one of the best in all dramas I have seen. The OSTS are excellent but sometimes it's inconsistent in which scene was used. All actor & actress acting & visual are good, but unfortunately for some characters (WIJ) it doesn't do justice since she is one of the main lead but get less screen time than guest role. Overall it can be an excellent drama with all reasons above but failed because of misdirection plot & lost value.
