Story aside for a second—there are multiple times here where I'm like, "No, what, your arm/hand cannot possibly be at that angle, what?!"
From the first chapter:
https://mangadex.org/chapter/433009/10 (his friend's arm in the top-right panel)
https://mangadex.org/chapter/433009/13 (his hand. Unless that's his pinky he's pointing with.)
