This was just an amazing drama ! When I started , I though it was going to be a average drama ! But boy was I way off ! It truly is a master piece ! How he tries to win back his love .Also, I love the different take on this one . Time traveling back in to the past and chaining things to make a better future (this reminds me of Nine Times Time Travel :where the main character travels back in time and figures out its consequences after words ) It is cute and nice drama !
