Outside of battle you can use it only on Bernard and Blacksmith for now. And it's not by going into the item screen, there is a new option while you are talking with them if you have a love potion in your inventory.
how about submissive and dominance potion? I use it and ... I don't see any effects....
Hm. It should change your position from Bottom to Switch from Switch to Top or other way around.
hmmm... The stats changed.. ok. Now i understand. Thank you, Hyao-san :3
I know not everything is obvious, all of it still need a lot of work and polishing. I hope it's not too annoying.
