Oiiiii. Oxygen is a definite must watch oh my goodness, my rewatch rate is 10 unless there’s a number higher than that in the scale. It is so smooth, so fulfilling oh it makes me happy, whenever I think of it. I told myself if I did not write a review on it then my taste in series is not mine any more. It is one of the best for this year ending I have seen oh I wish there would be an episode 2, but where it ended to was great. Oh oiii Oxygen had me happy every single time. Everyone just watching it, you won't stop smiling even when you get pissed off.
