Basically, I liked the characters and the plot, overall. I liked the messages of healing and also of forgiveness you can find in it.
But there were some things here and there that I disliked, like the humour. And the truth is I also simply hated how they dealt with alexithymia. Well, not hate, ok, but let's be clear : this is NOT alexithymia they are showing here. And it kinda makes me angry a bit.

Alexithymia does NOT make you lack empathy, guilt, remorse, whatever. THIS is what ASPD does. Alexithymia has nothing to do with ASPD.
Alexithymia is a disorder where you are unable to identify and express your emotions, with words but also with the right facial expressions. It's nearly impossible to say "I feel THIS", because your feelings are hazy and mixed up and you don't know how to express yourself nor feel comfortable enough to do so. You will more likely say "I think" rather than "I feel", for exemple. You won't express big emotions, yet this does not mean that you are not impacted by them even though you don't actively "feel" them, and this will translate as suffering from some psychosomatic illnesses. People suffering from this disorder usually are not risk takers or impulsive like a person with ASPD would, because with alexithymia you'd rather not be stimulated by anything or anyone and you'd rather not attract attention and be outside of the law like an ASPD person would. You're not going to kill someone impulsively because of alexithymia. You're just not. It does not affect your moral compass and ability to have empathy for other living beings, although you might have trouble understanding other people's emotions just as much as your own.

Wow ok so now that this rant is over, what's left :
Good premise
Some good characters
Good story overall
Good acting
Good pacing (imo)
Interesting relationships and an ok romance (yeah, am not a romance fan so I won't elaborate on that, but it was fine, they were pretty cute)
Pretty dark themes (abuse, trauma)
Important lessons

So yes, this is a good drama. It's entertaining, has lot of emotions, and the ending's pretty good. But this nonsense about alexithymia is just a bit much for me and is why I felt the need to write this review.
