I really wished that for once Ja and First would get a good script for a show, but sadly it wasn't the case. This show violated the most basic rules of writing: Show, don't tell; Delete any unnecessary crap that doesn't serve the plot or the characterisation; don't leave or start random threads that lead nowhere or have no starting point. Achi remained characterless without any backstory, there were so many unnecessary scenes, stuff was brought up out of nowhere and lead nowhere and the issues created and resolved were confusing as hell. The story between the doc and Mueang was making the most sense and 90% of their scenes were NC scenes.
The story between Achi and Punn could have been good, if they had leaned more into Punn waking up from his idol worship and realise who Achi really is and if he liked that person just the same (or more) because of his flaws. This was all they needed to set up a good plot. Instead, we still know nothing about Achi and who he is- aside from being famous, Punn is still a weird fanboy and they created this weird "he took notes" issue that made zero sense.
Writing wise, as well as directing wise (where did this weird overacting scene from First come from in ep 12? Achi barely showed any emotions for 11 episodes and then he acts like this out of nowhere? Wth?!) this show is a mess.
The only thing they didn't do wrong is paint abuse as romance, so they get a star for missing that trap.
