This review is a warning that the writers of this story might have meant well, but they missed the point by a landslide.
You cannot talk to suicidal people the way the pink girl does: without respect, yelling at them, encouraging them to commit, mocking them, daring them.
And the worst thing is: they frame this as positive. Her actions can and should not be condoned. You should deal with suicidal people, ESPECIALLY when your job is to prevent them from it, in a respectful, empathetic manner.
As said in other reviews, this is such a sensitive topic, and this show just doesn't deal with it correctly.
They deal with it in each episode overly simplified, as if you can just "resolve" it, as if you can fix years of trauma with just yelling at a person to be reasonable.
The only person that was remotely doing the right thing was Jun-Woong, but even his actions were incredibly surface level and half-assed.
The entire message of this drama is just incredibly harmful, and what it tries to convey to the viewer is just awful. It's not clear what the show is trying to explain, what it's trying to imply is the right way to deal with a person that's about to commit suicide.

But one thing is sure: this is not it. This is not how you deal with suicidal people, and this way of talking to them shouldn't be condoned in any way.
Yes, we only watched two episodes of this, but just given those two, and some other reviews, this show just fails entirely in every way. Except the casting. That really slays, but you can't fix a shit storyline and harmful messaging with amazing actors.
