When to watch it? I think the best moment to watch it is when you want to now more about what is being a woman ( or person capable of getting pregnant) feels like. And how serious is to bring someone to live who needs your all attention, but the hardest part is to not forget yourself in the journey.
How to watch it? With some tissues, obviously haha. But don't worry there are scenes when you can laugh, feel empathy, angry and try to solve cases, too.
Although there are 8 episodes, I believe a lot of people may get bored, because is very slow. But to watch it with someone will get a little more exciting or just watching from time to time.
DON'T RECOMMEND: if you are looking for a rom-com, or laugh all the time, or to make a marathon.
Tell me if this help you!
