You were exploring an ancient dungeon buried under a desert with your friend, Ryuken, when you both stumbled upon a treasure room filled with gold and gems, and one big gold pedestal with a lamp on top of it.

You took the lamp while your friend was checking out the artifacts, blew on the lamp, and rubbed it to check if the gems were real and not just stained glass

Suddenly, a blue cloud practically blows out of the lamp's spout, and when it dissipates, there's a tall, brown lady in a sexy two piece

Thank you, Master, you have freed me from my eternal sentence in the lamp, and for that, I'll grant three of your wildest wishes. Anything, there are no limitations. I'm not stingy like the other genies. I like showing my gratitude. Though, there's only one condition, you can't have refunds, and you can't wish to undo your wishes.

You wish for a girlfriend, and the genie snaps her fingers, but, a cloud of sparkles appears around Ryuken. And when the dust settles, there's a cute girl in a hoodie, looking at you with hearts in her eyes

You ask what she did to your friend, and she says

Oh, I made him into your girlfriend, Ria, only you know she was a guy. Everyone else, including herself, will remember her existence and acknowledge her as Ria, not Ryuken. Ryuken never existed. You have two more wishes.
