This series caught me unprepared. I was expecting the typical time loop cliche and some half-baked characterization...and I was wrong. 'The Long Summer of August 31' is a refreshing mix of gag humor, rom-com, and drama. The time travel is used as a background without much in-depth analysis, though the author does explore some tiny mechanics. I'm fairly content with downplaying the sci-fi/fantasy theme, as this allows the series to become a character study. I also love how recurring side characters build up the main duo's interactions - some of them acting as a catalyst by causing conflict that progresses their relationship. You might find both theMC and the FMC irritating, clumsy, or downright rude at different points. Maybe even insufferable, on both sides. And that's fine - it serves as a testimony of how well the author has encapsulated the general insecurities and volatility of being a teen.

Regarding the artistic approach, I really love how the mangaka reinforces the "loop" theme with how character interactions and events are structured. Quite often, you'd have pages where all the panels are identical, with just one introducing small changes. And of course, it gets endearing to see the layout pattern every chapter starts with - Takaya's slightly clenched fists, Kana's supposedly laid-back, but slightly stiff pose.

Additional bonus points for the "Why do you talk like a psychotic killer straight out of a David Lynch movie?" line and a few quite clever movie/music references.

This manga is a solid 8/10. It never gets old, always moves forward and surprises you in neat ways. Reading it in August only adds to the enjoyment.
