I really enjoyed this drama. The story is very well written. There are some little inconsistency like, his daughter's boyfriend finding out while watching an old video of him but his kids never even questioned it when they must have seen more old pictures of him than the boyfriend, but those inconsistency are very minor and doesn't affect the viewing experience. It's more about some little stuff you realiser after watching it. Honestly i was expecting way more stuff to not make sense considering he kept the same appearance.

The actors do such a good job, especially the main three actors, they are fantastic. Even the supporting cast does a great job !

The kids story was also very touching and seeing it progress made me very happy.
