How long has it been since you audibly laughed while reading something, and I mean truly laughing to the point that it hurts? As of writing this, I have read 52,753 manga chapters according to MAL, and out all of these, I know for sure that I consistently laughed at 49 of them, Boku to Issho's chapters. Somehow, the author made it so something static, as a drawing, can perfectly use comedic timing.
Furuya Minoru is truly a genius, someone who wrote the grim masterpiece of Himizu has no right to write this pinnacle of drawn comedy, but yet, he did.
