It is a little slow and can be quite heavy to watch at some part, but because of its storyline, it makes me want to watch it and i'm glad i finish it. It's worth it.

It's surprisingly easy to follow. Sometimes, fantasy show, especially one that involves "time slip" tends to get confusing, but not this one. It really is well executed and I really love each letter and its reply.

My favorite scene is when Namiya get to receive the letter from future. That's really touching that he gets to know he has lived a full, rich and meaningful life.

It's amazing how everything is inter-connected and how it ends in full circle. That last letter really wraps it up! Gist, it's SO good!!!
