So I am LATE to write my review.

My review will be from a viewpoint of someone who READ the original Japanese novel (in Japanese).

At 1st when this series got announced I was suprised and a bit confused. There's a LOT of Japanese BL novels being released every year and only now they decided to adapt another one to be a drama (after my Beautiful man). I need to thank bookwalker for me being able to buy a e-book copy of the novel. I previously read Egoist (and that novel hit me hard), overall the novel for Eien no kino was ok (but Egoist is a better novel). It was a sad read and more importantly the mofits/themes of the weather described in the novel really impressed me (which I think the drama does'nt take from the novel enough the only flaw I will give the drama).

ANYWAY ON TO THE DRAMA VERSION. Overall solid and a REALLY good adpatation of the novel. I am seriously impressed and envious that Senpai, this can't be love did'nt get this treatment (lol I am still salty about this).

Story: Mitsuru and Koichi are high school students (also dating), the two are enjoying their high school life until one rainy day/ Koichi is hit by a truck. BUT Koichi is somehow alive after the accident, slowly Mitsuru notices odd things about him and concludes that he is a "corpse". Still Koichi can be seen by a few but slowly the memory of Koichi is slowly forgotten. Thus the time that Mitsuru and Koichi have is limited by time..

Casting/acting: You will hear me say a lot that it was good/solid. I've never heard of Komiya Rio and Inoue Sora before this drama but after I am going to notice them more. Inoue Sora nailed that dull, quite and serious tone for Mitsuru and Komiya Rio got down the happy go lucky mood of Koichi (plus showing his toned chest a lot lol). They had good chemistry and acted their characters out really well. Nakamura Yuchi was really good as well when he did that roof scene (he was also in a pop team epic skit acting his heart out lol so respect to him).

Music: The opening song is seriously really good, but overall really ok OST matching the mood of all of the scenes.

Positives: How FAITHFUL the drama is to the novel. When I watched a scene from the drama I would question "Was that in the novel?" and when I went back to the novel it's there word for word. I would say that the drama version helped me like the novel version of the story much better before I watched the drama. If not the drama bought the novel version to life like how would Koichi act like a corpse and the drama showed that to me. It's very well shot and directed.

Negatives: As I said the very few positives I liked from the novel was the strong theme of weather described in some scenes. It stood out a lot to me when the truck scene happened in the snow and the image of the two walking in the snow spending their time together giving a metaphor of their time being like snow beautiful but short. It's lost in the drama version as there's no snow and just rain. I feel that rain is not that impactful compaired to snow. But still a very minor negative.

Overall: A one of a kind sad romance story. Some may find it a bit confusing (like why is Koichi still alive?) and too sad. Look past that and it's a really sad but touching romance story that Japan could of done.
