This show is the worst thing I've watched in a while...
Why is it normalized that Diao and Kuea are literally SCARED of the people that should love them?
How are Kuea and Lian supposed to be close
childhood friends even though they can't have a conversation about anything else than their relationship? Don't they have any common interests?

The characters of this show are puppets, flatly written to somehow drive the barely existent "plot" to some fan service, (there are so many unnecessary kiss scenes!) and then slip into the next recycled filler material about how they betray and gaslight eachother. These relationships are so unhealthy!
I was also just disgusted by the way that Hia Yi and Hia Lian treat Kuea and Diao like they are their dogs, it was infuriating! Two of the few things they did right in the show were letting Kon Diao stand up for himself and having Kuea be determined to call off the engagement (Only at first unfortunately). The glaring problems in their relationships were rather ignored instead of actually solved.

Despite the weird premise of the show I was genuinely hoping that the main couples were going to develop a meaningful connection over time, but there was barely any development. In fact for example, instead of showing his rebellious side more as the show went on, it felt like Kuea adopted a part of the "Annabelle " mindset more and more as his real personality. Just saying yes, smiling, shallow sweet talk and ditching the last bit of depth his Character had, until his breakdown when Lian proposed to him (The only emotional moment, I could actually get invested in). But afterwards he quickly paddeled back into mindlessly
obeying Lian.

Onto the next problem: Yi and Lian seem always keen on making Diao and Kuea as dependent on them as possible, taking their autonomy and controlling them, which is being portrayed as cute and caring, but it is plain toxic.

The "friendship" between Yi and Lian was also very lackluster, when they were meeting up they always just seemed annoyed and were missing, like pretty much any relationship in the show, any real common interests apart from being business partners.
Fortunately at least Kon Diao and Kuea's friendship was overall supportive and one of the few positive parts in the series.

Side note: I do appreciate the effort the actors put into portraying the characters well, but even good actors can't save a badly written show.

The only romantic relationship that wasn't absurdly unhealthy was the one of Syn and Nuer, they seemed to actually be on one wave length and even though their relationship was also lacking depth, it was still very cute and worth watching.

I truly believe that this show was made for a kind of thirsty viewers who don't really care about the plot as long as there are plenty kissing scenes between two hot actors (even if the kisses don't really feel romantic), as this is the only way I can explain why this show isn't as widely called out for what it is:

(also tldr) A substance lacking excuse for kissing scenes with a plotline almost exclusively consisting of normalizing unhealthy relationships, a few good songs and 10 minutes of preachy dialogue in the beginning and end, that can't be taken seriously, because nothing said is actually reflected in the show.
They should have called this series "normalizing toxic relationships 101"

I'm very disappointed, what a waste of time!
