The webtoon is so different than this. The story, character's, development. I'm so disappointed. They have an opportunity to do a unexpectedly development like the manhwa but they didn't. I'm so angry too because they ruined the grandfather character.

So please read the manhwa and you can understand what I'm saying and maybe you should think like me.

sorry for my English haha
Así que bueno leerse el manhwa pq esta burrqda de dorama me decepcionó. Por eso siempre las adaptaciones a live action son tan difíciles de aceptar. Uno de los doramas que lo hizo bien fue Whats wrong with Miss. Secretary Kim? pero bueno, cosas que pasan.
