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.
I'd recommend 'The Remarried Empress'. It combines drama, romance, and fantasy elements really well. The chemistry between the leads is palpable and the story has depth. 'See You in My 19th Life' is also good. It has a touching and heartfelt romance that tugs at your heartstrings.
Some top BL manhwa series include 'The Third Party' and 'BJ Alex'. 'The Third Party' has a compelling storyline and 'BJ Alex' is known for its beautiful art style. It really depends on your personal preferences though.
One of the manhwa with an amazing story is 'Tower of God'. It has a complex and engaging plot that follows Bam as he climbs the mysterious tower filled with different challenges, diverse characters, and a world full of secrets. The story gradually unfolds, revealing the dark underbelly of the tower and the true motives of those within it.
