You are young and smart but your thick-lensed glasses make you a persona non-grata at the feast of life. Nonetheless, an unexpected chance turns up for you to become a man. The only thing is, during sex you find out that having it teleports you to other worlds... which you’ll have to save from global disasters and catastrophes. But for a start I should try to return home. How? The same way I got here – find a girl and try not to fall in love with her. Because if I do this thing right I will probably never see her again...
