Your choices, in order:
start : You have a magic pencil that can draw and erase things IRL. You drew by accident Emma, a 35 cm tall woman that explained you everything
keep Emma : to thank her, you drew her wings and made her a island house painting for her to live into.

You decide to go show the pencil to your girlfriend Sandra, who is roughly your same age and lives just five minutes away from your house. You send her a message saying that you have something to show her and she replies to come over with a smile emoji.
You eagerly walk to her house, keeping the pencil in your pockets, twiddling it every once in a while. Arrived to her apartment complex, you ring her intercom and she answers joyfully to come upstairs.

«Hi, Jimmy! » she greets you with a hug, letting you inside «So, what did you want to show me?» She is wearing a simple t-shirt, soft magenta pants and slippers, casual indoor apparel. You are at that point in your relationship where you don't have to dress to impress.
