This first episode was very slow placed and a product placement for the app LINE.
It was rather hard to keep interested in this episode as the two main characters were not that interesting and were shy with each other, there might be a reason as if something happened in the past, hopefully to make this an interesting story but nothing was mentioned in the first episode.
The OP itself was an interesting one because they had scenes, which happen in the first episode itself, but I wouldn’t call it spoilers. I didn’t know this of course until I saw the scenes repeated when watching it.
I have only completed 2 series from feel. Studio but I can’t really tell if I like what they are doing in the animation wise. The style should I say. I guess it’s a bit of an experiment, it seems that each character has some sort of light reflecting off their side of the face. But not only that sometimes they use CGI with the background characters and this looks off place when combined with non-CGI modules. I personally don’t like the use of CGI when it’s not need or used correctly.
I would admit I didn’t enjoy this as much I thought I would. And I don’t have much of an impression on this series. I will watch episode 2 to see where exactly this series is going and is there a more of setting than School.
I would recommend this if you are a fan of school, romance genre, but with everything else that was my subjective opinion and you may like the animation, the cgi use and the cast of characters.
If you would like to watch this series, you can do so on Crunchyroll.
