Love Potion.
You recently came across a bottle of pink liquid that was a real love potion; the most important thing is that you can use the love potion at your discretion; everything is entirely at your discretion; options when something like this happens, a lot of thoughts can really run from options for action.
What happens can happen at different times and under different circumstances, this is also at your request, you yourself can figure out how the love potion came into your hands, perhaps you bought it somewhere, someone gave it to you, or you just found it on the street or something else
If you wish, you can write your own story, if you wish, you can come up with a story where you drink a love potion, everything is completely up to you, you can also come up with how the potion will affect the person who drinks it, for example, after a person drinks the potion, strong love may arise or the person may become a yandere, but this is again only at your discretion
