One story I heard was about a woman who found out her partner was cheating. Instead of making a scene immediately, she quietly collected evidence of his affairs. She then sent an anonymous package to his workplace with all the proof, which led to him getting fired and his reputation in tatters.
I think 'Solo Leveling' has a great story. The concept of a weak hunter becoming the strongest is very appealing. The story is full of action - packed battles and the protagonist's growth journey is really inspiring. There are also various mysteries and political elements in the manhwa's world that add depth to the overall story.
The reason you think it's the best manhwa could be that it combines elements like an exciting adventure, heartfelt emotions, and a fresh perspective. The quality of the illustrations and the depth of the story might be what makes it stand out for you.
