Yi chan, I felt bad for him add the end. This character had to go through alot..?? the actor did justice with him.
Overall, the plot is alot of people's dream I guess,
want to go back and fix things....
but what about the grandpa, I mean from the it was understandable he was mr.viva/the dieti,
but how did he got Power... ?
and another plot hole was like, how do you not know someone is living at your house, using electricity, and the hole place . you didn't put any caretaker for the house, never call them or anything???? ??
