This is a review on both "Seven Days: Monday - Thursday", and "Seven Days: Friday - Sunday", because really, the two should be seen in conjunction with each other in order to get a complete viewing experience as both parts make up the whole.

STORY (No spoilers)
Actually, I read the manga (also helpfully entitled "Seven Days") on which this short 2 episode series is based on, long before I realised that they actually made a live-action version of it. Having enjoyed the short but sweet manga itself and having never seen a proper live-action Boy's Love series prior this one, I was curious enough to check it out.
I will get into the acting for this series in another section but story-wise, both episodes were amazingly faithful and accurate to the manga itself. Here is a short list of just how accurate it was:-
a) The manga itself consists of 2 volumes. The 1st volume being the Monday to Thursday sections, and the second volume having the remaining Friday to Sunday sections. The way the series is split is exactly the same way.
b) Dialogues from the characters are almost word-for-word from the manga.
c) Scenes and events that happen also mirror very closely to those in the manga.
d) What impressed me the most was that even the styling - from the hair, to the way they wear their school uniforms, to even their school bags and the way they carry them, mirrors that in the manga.
It was really as though the manga itself came to life - there were hardly any deviations of it in the live-action series. So, for those who read the manga and enjoyed the story, you would be surprisingly satisfied with this production.

Story-wise, the synopsis is a pretty good summary so I am not sure if I have anything further to add. It really is a simple premise of what started out as a high-school tease between 2 boys to date for a week (seven days), ended up creating feelings which neither were prepared for, and their various insecurities and misunderstandings arising from that. Like the sound of it? Then do watch. If not, then feel free to give this a pass.

Another thing to note is that the pacing of this live-action short series is rather deliberately slow. I believe that the production team and the director had in mind a pace that was meant to deliberately focus and pause onto the main characters, either to emphasise a scene or an emotion, because this is done consistently throughout the show. It's almost manga-like: you know, that scene where the 2 main leads stare at each other and the wind and leaves just keep blowing by... yeah, that kind of manga-like feel. If you're not prepared for it, it may sometimes appear as if the scene is being paused, but it's actually a deliberate drawing out of the scene. Some people might find this draggy or boring or weird, but I personally see it as an artistic approach and directorial style, and quite enjoy the slow, deliberate pacing of the show. Most Japanese series tend to be rather snappy and excitable so a mellow, calm-almost-to-stillness show is rather interesting and refreshing as a change.


ACTING/ CHARACTERS
I've mentioned how the whole setting, down to the styling and the outfits, were practically a mirror to that of the manga. Now how about the actual portrayal of the characters?

JAMES TAKESHI YAMADA as Shino Yuzuru - the senior whose cool looks apparently seem at odds with his playful and unpredictable personality. Looks-wise, I think James does have that cool look befitting the character but I had hoped that he could have acted a bit more "fly-away" or ditzy just to emphasise the dichotomy between his looks and his personality which many people around Shino keep banging on about. It would have made some of the comments from supporting characters a bit more believable and understandable. As it stood, I felt that we had to just accept what we are being told i.e. that Shino's personality is very different from the way he looks. More tell, rather than show, in this aspect, for me. Having said that, I thought the rest of how James portrayed Shino was well done. The curiosity, the internal dialogues, the progression of feelings and its by-products of uncertainty and jealousy - I thought these were all expressed pretty well by James in his role.
PS: I also liked the way he holds his bow and arrow, and his shooting stance. It did look very cool and natural.

TOMOKI HIROSE as Touji Seryou - the good-looking junior whose inner desire to find The One has led to an appearance of being indiscriminate when it comes to dating and partners. Looks-wise, I personally found Tomoki to look too old for the junior he should be portraying - and not a little older, but quite a lot older, which was was initially rather jarring when I first started watching. Looks aside, Tomoki did not do too bad a job in bringing out the emotions and the feelings of Touji onto the screen. His acting did not come across as natural or as at ease as James playing Shino, but neither was it so bad that it was too awkward to watch, so I would consider his portrayal to be serviceable for the role.
PS: Tomoki's shooting stance looked awkward, stiff and unnatural to me, compared to James and the supporting cast. Pity because he was supposed to be rather effortlessly good at archery and it does not really come across in this live-action adaptation. But this is a minor quibble.


MUSIC
Befitting the deliberately slow pace of this show, the background music is instrumental, mellow and rather poignant in tone. I thought it matched the mood and the pacing of the series well and personally found it to be a good enhancement to the scenes in bringing out the moment or the mood. Nice.


RE-WATCH VALUE
Seeing as it is a very short show of only 2 episodes or parts, this is easily re-watchable. Overall, it is quite a well done series, barring my minor quibbles outlined above. I can see myself viewing it again.
