okay I have to say that the concept of the drama is pretty unusual and kinda refreshing to see older lead, although I had a major problem during this and I don't know if I'm the only one, which is I didn't like how she was falling for someone as her grandson age.. now don't get me wrong I don't mind the age gap but I think this could be a bit too much.. and also I could get pass through that if things in the end wasn't as it was! for me I wished if they changed that a bit.. and I couldn't get why did they made her older than the manga? but other than that the drama is pretty innocent and sweet, it's very light and enjoyable to watch I liked all the cast they're all awesome specially Rei >
