Your in a world where most monsters are girls. so a world with monster girls. your also in a world where they either make you gain weight or inflate you in some way. Your local potion dealer has something called a "Potion of bee friendship". You ask them what it is

"Oh that one! So basically, if you drink a bottle then one beegirl will come and help you on your adventures! though, every time you drink one of the potions you get inflated honey..."

You buy it, if you didnt then why you here?
