I remember reading the original one-shot and feeling not much of anything, so I did not give the adaptation a chance when I saw it first published. Now I feel nothing but anger at my past self for denying me this absolute gem over superficial impressions. This story is so well paced and enjoyable that I felt giddy all the way through.
Usually I don't consider myself an art critic, I have no eye for such things. A story's strongest merit for me will always be the writing. And yet... this manga most definitely has the best expressions in any manga I have read in the last years. Certainly there are comedic series with exaggerated expressions, but this manga makes it all seem to natural, cute, impactful! You can tell every emotion so perfectly and the shifts are amazing. When it comes to facial expressions and sense for anatomy, I think this author is top of the genre right now. Kudos.
