...this drama actually does much more than using the little SciFi element for gender switch. It especially raises questions and addresses issues about human behaviour you have in any kind of relationship, independent of gender and makes you question yourself in a good way.

The acting and character development was shown in a slow but needed pace and done very well by all actors. Still it delivered with some unexpected turns and twists to keep you going and lots of thoughtful dialogues and shared thoughts of the protagonists. The Theme song was nice, rewatch value not too much regarding the story, but good to catch up on some thoughts here again once in a while.

Just, I'd say, how things are resolved felt a bit too lightly. E.g. as I think affection between people is also partly created by visual aspects of the persons involved I'd guess in reality it won't be that easy going like shown here.

But nevertheless the drama can be seen as a very valuable and carefully crafted pleading for an open mind especially regarding any relationship between any gender. There's not too many gems out there like this, and more are needed.
