the improvement in the art, the story, character development, how they fight through their unhappy pasts with the presence of another, slowly understanding eachother more and more everytime they wake up next to eachother, fighting through problems together, their love is growing everyday but it ended now *sob* its sad seeing how one of my first manhwas ever just ended, I remember reading this like 2 years ago and I absolutely loved it, beautiful manhwa.
