I read this a long time ago and I particularly don't remember why I loved reading this so much but from a technical view point there are several points I would like to make on why this is an amazing manhwa. 1. Really good artstyle which stays consistent. 2. Characters are well written and have depth in their personalities. They stay true to their roles and their personalities. 3. The plot is amazing and unique. I honestly don't know how it hasn't gotten adapted into a drama yet. It has both light-hearted wholesome moments and hilarious comedic moment and dark and heavy moments. As a story it isreally amazing even without the characters doing their part.
4. The story is always moving. I don't remember one moment where I felt like they were dragging it.
