I devoured the first 10 episodes. Very good episodes that are easy to watch. The two main actors perform excellently, and the story is engaging. However, it seems that with each episode, unnecessary details are added, making one wonder why... The characters are in constant danger, without respite; they practically have a subscription to the hospital...
What happened to Ji Sang U and Na Yu Ri's show (by the way, in the end, these two characters served NO PURPOSE AT ALL)?

But what was the point of the entire last episode, seriously?? They just needed to have the villain die, END OF STORY.
Why make the male lead disappear? Sure, you feel sorry for the female lead, but you've known her since childhood, been married for 3 YEARS, and you know she knows the story, so WHY???? What he didn't want to experience—living in uncertainty, not knowing if his wife is alive—he ends up imposing on HIS OWN WIFE! The entire last episode is filled with confusion, shifting from dream to reality, past to present, without any transition, making it incomprehensible. It was just ridiculous; throughout the episode, I wondered where it was heading, and then the part in Africa, seriously??

Everything was going well; why half-ruin the drama at the end? Might as well have stopped at episode 11 or skipped directly to the end of the last episode...
