There’s an Autumn Sale on Steam going on right now and lots of otome games got discounted a lot (like HOLY S*IT, you can get Amnesia for roughly 3$ ).
Check the list out HERE. The sale will end on 1st of December !
(PS: If you’re a fan of Idea Factory JRPGs, you can get Fairy Fencer f and Hyperdimension Neptunia: Rebirth for more or less 6$. I suggest you check the full discount list if, like me, you like a variety of games)
