MORAL OF THE STORY: [spoiler]Do NOT enter a location when you see people wearing PPEs. (If you are a nurse, you should know this already.)[/spoiler]

I applaud the screenwriter for not shying away from [spoiler]killing a major character[/spoiler]. There are very few screenwriters who are brave enough to do it, often screenwriters choose the "[spoiler]they happily lived ever after[/spoiler]" route.

[spoiler]However, as the intro to this post hinted, I do not approve the sudden stupidity of a major character just to get that character terminally ill. Go Mi Ho was a nurse. She is intelligent and full of wisdom. Where did her intelligence AND WISDOM go in the cave sinkhole episode? Then after that episode, Mi Ho became intelligent and full of wisdom again.[/spoiler]

[spoiler]In that one episode, she suddenly acted a hero when it was never part of her character, and after that episode, she never acted a hero either. She is intelligent AND WISE. She took calculated risks. She was no hero, before or after. But in that one episode, she acted a dumb hero which led to her getting exposed to deadly radiation.[/spoiler]

Sure. There are people who would have done the same as she did but that is a rare thing most especially when the people escaping a disaster are wearing PPEs, [spoiler]and you happen to know as well as corrupt and evil the operator of that cave. All for what? For that character she saved to only die WITHOUT contributing anything to the plot after he was saved.[/spoiler]

[spoiler]That episode. Go Mi Ho suddenly throwing her intelligence and wisdom out the window was only meant to get her terminally ill. No more, no less. It was very weak. They could've have used a contaminated bottled water or fish planted by Choi Do Ha, or some other method other than letting her do something out of her character.[/spoiler]

People rarely do something like what she did unless they have a very, very, very strong conviction [spoiler]which Go Mi Ho did not possess. She took calculated risks for her husband, that was the entire driving force behind her. Her saving people begins and ends with her working as a nurse, outside of it she didn't do anything.[/spoiler]

Again, good job on not being afraid [spoiler]of killing a major character. But very bad job on how to get that character terminally ill.[/spoiler]

From 10 stars, it's down to 8 stars.
