Comparison to the US Version:
As someone who has seen the american version I can tell you its very similar to the US version in terms of setting. However it feels a little softer and more innocent in a way. I personally enjoyed it more than the american version.

Relationships:
The interactions and conversations were wholesome and it felt very real. Compared to other japanese dating shows I already watched, the contestant didn't came across like they were the usual reality TV characters which I liked. However this might be a point where other people would say that it makes it less interesting than other shows.

I would definitely recommend the show if you want something nice to watch that is both romantic but also feels real.
