After finishing the series, it almost felt like a relief because I watched every week hoping there would be a little more to spark my interest but after 13 weeks I can say that overall it was just a plain drama with little to no conflict at all.

If you enjoy a light hearted drama with not much to think about, this would be a nice one to watch over a weekend but if you want depth and quality, this would not be for you.

The simplicity of the story was really lovely to watch and the relationships were just pure and cute with no 'am I gay? No I only like you' trope which was refreshing. The relationships between Solo and Gui as well as Phu and Kao were overall really enjoyable and both couples had cute chemistry. The third couple was just shambles, I could not care less about them, I wouldn't even be able to name the doctor. Often feeling the need to skip their scenes, the third couple really did not add anything to the story except frustration.

The only actor I think that did a good job is the one who played Kao. He was very natural and played his part incredibly well. All the others were lacking in some aspects, whether that was facial expression or delivery of their lines. I am not sure whether it was because of the actors or the director not helping them and giving them enough guidance.

The OST of Oxygen was really nice to listen to and I found myself not wanting to skip it very often, however, the other aspects of the drama in terms of music were pretty awful. The sound effects were bad and at times the background music was abruptly cut with no real transition.

Overall, an okay drama with not a lot of substance. I wouldn't personally rewatch.
