He's really living the dream of postmen...Or rather, every guy ever.
A busty housewife in a naked apron, A perverted introverted glasses girl, a pettanko tanned schoolgirl...And going by that ending, even having 4P with them all on a regular basis? A veritable harem is what he has...
Though I guess being born with a pheromone that drives the ladies wild is essentially a free pass to being a Hentai Protagonist...Which is a essentially the title of someone who seduced even lady luck herself.
