In the first 10 chapters, all I knew was the FL and ML being in an arranged marriage for alliance purposes, that a long war just finished, that the ML needs to sort out issues in his hometown territory, and that the FL plans to embark on a journey to find traces of her theory about the main enemy's survival after the war. Towards chapter 29, an intriguing prophecy was seen by the FL, involving the ML and the main enemy. This foresight then sets the direction of the story, which was primarily the FL's quest to save the "world", or all living beings who can be potential victims of their enemy who's greedy for power.

A toxic trait of someone as capable as her is that she tends to deal with the most difficult and dangerous tasks by herself. This is her form of self-punishment for covering her guilt, for defying her village's traditions by using magic to kill, even causing a strain in her relationship with her mother. She eventually learned to ask help, lowering her pride to ask for help of her counterpart in the Temple, the more influential organization in the empire, to defeat their common enemy. However, their enemy in this story isn't ordinary anymore. He's an overpowered ancient being, brought back to life by the revival of his new disciples. Some readers expected that the FL should have been the one, personally, who defeated the enemy. But it turned out she wasn't. BUT her ideas caused the enemy's weakness, and the growth in her character (no longer looking to punish herself, but to move forward, acknowledging the love she receives from people who care about her) disabled the enemy's power source in the final battle. So she did her part in that sense, and the rest is all teamwork. I mean, the other units weren't there for nothing! I think that's what other people ignored, the fact that her character growth wasnt about personally defeating the enemy, but being a significant contributor in the enemys defeat by finally overcoming her own personal conflicts.

However, for his character growth, he needed to learn to open up with her more as her partner. His growth in this aspect was also central to the plot. Now on the aspect of his abilities, I find it unfair that there isn't much criticism of him "being a burden" when it took a whole mission, led by the FL, to save him when he was kidnapped in one arc. All the Korean readers' criticisms were directed to the FL, on how she wants to take on missions alone, but end up getting herself severely injured. But none for the ML, even if he also experienced the same when in fact, there was an arc when the FL also rescued him. So was he any less capable? No, it's just that the plot needed them to grow as a couple, and to do that, there had to be plot points that prove they have each other's backs.

The enemy is an ancient being who sucks up the life force of others to gain strength, earning him an unfair advantage. That's why it takes more than just the empire's brilliant sorceress to take him down. Reading the final battle scenes with this being truly made me worry for the characters I cared about. That's how threatening the story's villain was.
