The whole drama,cast,acting everything is good enough. But I think the ending should be changed .Except the ending this drama deserve 10 out of 10.It should be a second season where we can see that the male lead was not died.The security who exactly looks like the male lead ,he should be the original male lead. when I watched the ending I thought it that the male lead was not died and he was kidding with the female lead.But I was shocked when I completed the drama.But it was too good.And I will wait for the second season .I hope in season 2 they will be together.
