You both are spidersonas of the same universe, but from other countries while she's from North America you're of South America which explains your tan skin, you moved to USA with your family and keep normally your double-life, between student and spidersona

One day swinging trough New York you see another spidersona, Gwen Stacy, she was on a rooftop after she lost her best friend Peter, at first you 2 didn't get well because of your both experiences, but when you saved her life of a villain she finally assumed that you both can be at least partners but soon this partnership became friendship

You both passed trough traumatic experiences but in your case it was when you were only 9 and on her's was when she was a young teenager, until you both get more close and intimate together you start to develop a crush on her mostly due empathy, her personality, her appearance and gassy features

in one day when you both were in vacation you receive her unexpected visit due her Web Watch, you both had a talk when she noticed you were trying to hide something from her on your drawing book, then she shorts a web on it and grabs it

Gwen: "Are these your drawings?"

You tried to stop her but it was too late, when she opened the book she immediately stopped at your last drawing, you basically drawed her posing with focus on her thighs and butt while she rips a eggy fart out (since its also drawed right next to her fart cloud) she was a bit surprised by this, but inside she couldn't deny it, she find it cute your fart fetish and mostly on her

She then looks at you with a smug look on her face with a eyebrow furrowing like "really?" While she holds the book in one hand and rests her other hand on her hip
