What a good manwha to end 2023, really deserves all the attention

this was too good. like i was looking back on manhwa's i used to read and didn't follow up, and damn was it the right decision. this really is mind boggling, the concept is so unique, it keeps you on your toes and it really is the master mind of giving hints without fully revealing where the story is going. its so good also because it ends in an happy ending, and doesn't make the character face an unnecessary ending
