Sorry, English isn't my first language, but I'll try to write some thoughts.
First of all I liked the idea of having older cast, the ML reminds me of my grandpa<3. I also liked the moral of the story - to never give up and how you are not too old to dream and make your dreams come true.
However I found this drama a little too boring. I even started watching another drama but still decided to come back this one. Maybe this was too slow- paced for my liking. Like I get they want to show everyday life but at some points of this drama it felt like the story wasn't really going anywhere.
If you're looking for something nice and touching to watch and don't mind the story being slow and the lack of romance this could be the one for you.
