The 'A Bad Friend' manhwa's main plot centers around the ups and downs of friendship. It follows the characters as they encounter various situations that reveal the true nature of their friendships and force them to make tough choices.
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.
