I waited until the last few episodes to write this review and I think there are mainly 2 types of viewers:
1)the ones who have seen "Go Ahead"
2) and the ones who haven't

I am part of the audience that has watched go ahead and that is why I believe I found this drama to be mediocre...So keep in mind that my review will highly be biased based on the original

Plot:
1) As Go Ahead is a Chinese drama it has around 40 episodes and as a result there was a lot of character development and side plots that were important to the story, this drama obviously had to get rid of some of them but for the same reason it felt lacking overall

2) There was also too much focus on the romance aspect and I think it would have been much better if they just took inspiration from the original and focused on the slice of life part...I also felt like the dads didn't give off the same vibe...in the og drama the dads have a whole persona of their own but this show just seems to dumb it down


Acting:
The leads have absolutely no chemistry..Hwang In youp as an actor is fine but in this drama he just looked awkward the whole time
the crying scenes weren't sad, the romance scenes weren't magical and the only saving aspect was maybe the comedy

Other thoughts (may contain some spoilers):
Why were all three of their careers changed? It was such a minor detail that had huge implications in the og because in that drama kim sanha was supposed to be a dentist, her a craftswoman and business owner and haejun was supposed to be a pastry chef, their career choices (especially the brothers) were supposed to show how dependent they were on juwon and it played a pretty significant role

The friend group wasnt the same!!

Haejun's character confessing his love in og shows that he was desperate to be included in their family dynamic and that his abandonment issues forced him to create feelings in order to belong...

The side character were only plot devices for the leads and they lacked depth!

Conclusion:
Anyways to conclude, If you havent watched go ahead you may like this show but if you have its just going to seem like a cheap remake I would recommend that everyone watches the original if they have time, but If you don't this is a decent watch (if you watch with a blank slate with no bias you may like it more than I did)

I doubt there is anyone who can argue that this was better than (or even on the same level as) the original.
