Just watch the drama on Viki, the thoughts of Tae Oh are translated there if you are having any difficult ies.
There is a reason why his thoughts are not translated. It was intentional. They are all translated at once in the last episode. Even though it might be a little frustrating, it makes much more sense to watch it like that.
I was annoyed at the start, but then I accepted that I could only understand some words. When they finally revealed it all at once, I was actually happy that they did that.
I really hate love triangles, and I can't stand SMLs who do not know when to give up. But this SML is something different. He is the real MVP of this show. He is actually the one who pushes ML and FL to be together because FL's happiness is the most important thing for him.
I really like the use of 3 different color schemes for storytelling: black and white - world without Risa, extremely bright colors - world with Risa, faded colors - memories. It is brilliant. Understanding what those color schemes represent is a part of watching experience, so I will mark this as a spoiler. Unfortunately, many people will not like this movie because FX looks extremely cheap, and some other people will say that the story is slow. If you ignore all the flaws and concentrate on a very nice and touching story and great storytelling, it is actually not a bad movie.
I only see the first season (12 episodes) on Netflix. It is possible that second season is available in some regions while it is not available in others.
