On one hand its kinda cute how author managed to kinda create a world that is like an in-between the 1:5 ratio manga and the 1:39 one.
The depression of being lonely girl progresses, desperation slowly changes into full blown "hunting". Dudes change from cocky "choose all you want from the female buffet" types to being actually scared. In the 1:39 men are even forced to donate sperm to try to make the world still be there and not die out.
But this dude is so retarded its just kills any joy from reading this.
He has 4 things in his head, air, string and two dead brain-cells. The brain-cells were fighting for 3rd place, one killed the other - the killed one was the one keeping them both alive - so the winner brain-cell died out of starvation. Air is there to balance the pressure with the outside world. The string is there to keep his ears from falling off.
