The protagonist has apparently reincarnated multiple times and is still 17 years old. Having defeated a demon lord and a demon god, it's obvious they should have a lot of experience and strategies. I expected them to be strong once their attitude changed. I read a manga with a good story because it made sense that the character was intelligent and experienced. The characters were good, but I didn't quite understand why the protagonist's attitude was different, and it made me lose interest while reading. Maybe I'm wrong, but in my opinion, manhwa is more adaptable to read compared to Japanese manga. I don't know why, but for me, it scored a 3.2/10.
