I wonder how many other hear in their head "Take My Breath Away" by Berlin while reading this one? I do, and I suspect the combination of "Slow Motion" in the title and the 80's that is causing it.
I wish the author would have leaven out the triangle trope. As all is not translated yet, I do not know how it will end but I am tired of this trope and already the very first time Koizumi appeared I took a break from reading and begun considering to drop the whole manga. Why do so many authors feel a need to add unnecessary chapters by sowing discord between the main characters by using a third character? If one really would want to add more chapters then add more chapters with the main characters development and relationship development (things going forward and not backward). For example, I think it is ridiculous how afraid they are to show their love for vintage stuff. Why not create some proper development there? This I say as someone that likes older stuff too and I am not afraid to be a bit "odd".
