...Why does it feel like this is a scene that actually happened to the mangaka? Except I assume less of the creepy creep behaviour mc was doing at the start (I keep on seeing it in manga and anime, but noone acts or thinks that way in reality).
On that note, why does it feel like I know people who did similar stuff in uni, except they were far less stealthy about it, and as a result far more discreet (no conspicuous behaviour like pulling a bottle out of their privates - just treat it like any other people would treat their water bottles)? Like that one guy I remember had a metallic bottle he brought to every exam with some form of hard liquor in it (he let me smell it when the convo turned to his cool bottle).
