Wow, I am quite surprised by the negative review. Let's address each point:
Firstly, those who criticized the main character (MC) as a doormat easily manipulated by nobles and uninterested in others haven't even experienced the initial story arc. It's unfair to judge without giving them a chance.
Regarding the OP (Overpowered) criticism, it's true that the plot sometimes justifies the MC's abilities, but it's not entirely unjustified.
As for the romance, opinions vary. Some prefer the MC staying loyal to his original love, while others wish for him to open up and appreciate other characters, considering their efforts. It's subjective.
The action scenes are commendable, actually. The MC's strength isn't an issue; it's the lack of challenge from his surroundings that makes his feats seem impressive. In the Spirit Village, his actions would be trivial compared to the spirits.
The main antagonist, the demon summoning the hero, and the other villains have ample room to show their cunning, often taunting and dismissing the MC during battles.
The romantic development is gradual, with a dedicated arc to build feelings, which adds depth to the story.
People seem to drop the series due to expectations that don't align with the genre. It's set in a noble society, so politeness and flattery are part of the dynamics. The story relies on unexpected twists, like the hero's arrival and the MC's pursuit of justice.
In conclusion, the series may not cater to everyone's tastes, but it offers a well-rounded narrative with its own pacing and character growth, especially in terms of the MC's actions and the romantic subplots.
The only part I cannot comment on is the romance, but personally, I believe some characters' happiness is justified after their struggles.
