Ok so where do we start? I have seen many people having many different opinions about this serie. A lot of people say it's boring and I clearly see why but I have to disagree a little bit. I myself wasn’t very into it at first because nothing really happened? The characters didn't have much personality and it felt overall pretty boring and dragged out. However I personally came to realize that this serie takes some time to kick off, maybe a little too long though. The characters as well, they all grew a little stronger later on and I started to see more colors in their personalities.
Sadly this took way too long and most people got bored before getting to the better parts. I can't exactly blame anyone because I was very disappointed as well but with a bit of understanding and lots of time I eventually got very attached to the characters somehow.
I did not get into the straight couple though (not because they were straight ofc) but their story just felt confusing, toxic and I just did not feel any development or emotion watching them. It was mostly uncomfortable.
At the end of the day, Oxygen actually had very loveable characters if you're willing to give them some time. I did not like how long it took for that to happen though, it was way too slow and dragged out in scenes where nothing really happened. But after finishing the show I really came to adore Sologui and even more, Phukao.

ACTING:
I am not sure how to judge the acting. I'm gonna be honest and say the acting could be a bit too stiff. Especially from Petch who acted as Gui, but considering it was his first acting job it seems understandable. I also believe his character were supposed to lack a strong or colorful personality. Okay but on to my favorite, Boss. Boss acted as Kao and I personally really enjoyed both the character and his way of giving life to it. Kao was a very kind, music loving guy with a confident but very understanding personality. The tone in his voice and face expressions suited his character well enough at least.

OST:
Here we have something I loved. The OST of this serie was amazing. Never skipped the intro even once. It was catchy and fitting to the serie. A nice melody with nice lyrics. Yes this is a song I will remember for sure.
