Y/N Matthews is fifteen-sixteen years old—the same age as Riley and Maya, and one year younger than his older brother Joshua. For as long as Y/N can remember, his family has expected him to be their daughter. But Y/N knows himself differently. He’s a boy, and he’s been trying to live openly as himself despite his parents refusing to accept it. They still call him their daughter, use his old name, and insist that he’s going through a phase. Y/N has learned to keep his head down around them. Correcting them usually leads to arguments, so he often stays quiet instead. When Amy and Alan decide to bring Y/N along for Christmas, they travel to New York to spend the holiday with Corey, Topanga, Riley, and Auggie. Y/N has never met most of them before, and he’s nervous about what they’ll think when they realize he’s a boy. The Christmas gathering includes Corey, Topanga, Riley, Auggie, Maya, Shawn, Amy, Alan, and Y/N. What Y/N doesn’t expect is for Corey and Topanga to immediately notice how uncomfortable he becomes whenever his parents refer to him as their daughter. And Riley and Maya aren’t exactly going to let their new friend sit silently in the corner all night.
Riley Matthews and Y/N have been secretly dating for a while, and they’re completely happy together. Unfortunately, Cory and Topanga don’t like Y/N and believe they’re a bad influence on Riley, so they forbid Riley from hanging out with them. Riley refuses to let that stop their relationship. Whenever the house is quiet and everyone is asleep, Y/N sneaks through Riley’s bedroom window. The two spend their nights whispering, laughing, and trying not to get caught. But sneaking around is getting harder, especially when Cory and Topanga start noticing that Riley keeps disappearing at night. One night, Y/N sneaks in like usual… only to hear footsteps approaching Riley’s bedroom door.
Y/N is a troubled kid who grew up with both of his parents, but neither of them ever gave him the love or support he needed. Their constant neglect and toxic behavior left him angry, defensive, and convinced that nobody could truly care about him. His grades are terrible, he gets into trouble constantly, and he has completely given up on his future. Like Maya, Y/N uses sarcasm and anger to hide what he’s really feeling, but unlike Maya, he refuses to let anyone get close enough to help him. When he becomes part of Riley and Maya’s world, the group slowly realizes that beneath all his anger is a kid who desperately needs someone to believe in him.
Starkwell University is the kind of college where money talks. The campus is luxurious, tuition is ridiculously expensive, and most students come from wealthy, influential families. The Avengers are no exception. Tony Stark, Steve Rogers, Bucky Barnes, Natasha Romanoff, Thor Odinson, Bruce Banner, Clint Barton, Wanda Maximoff, Sam Wilson, Peter Parker, T’Challa, Scott Lang, and Rhodey all attend the prestigious university thanks to their families’ wealth and connections. Then there’s Y/N. Y/N didn’t get in because of money, connections, or a famous last name. They earned their place through their grades—and their scholarship comes with one terrifying requirement: Maintain a 4.25 GPA. If their grades drop below that, they lose their scholarship. And without it, Y/N can’t afford to stay. So while everyone else is enjoying college life, Y/N is constantly studying, finishing assignments, attending lectures, and spending hours in the library. After paying rent and school expenses, there’s barely anything left for food. Ramen. SpaghettiOs. Cheap cereal. That’s dinner most nights. The Avengers don’t understand it at first. To them, grabbing expensive food after class is normal. Buying new textbooks without checking the price is normal. Going home for break without worrying about rent is normal. But slowly, they begin noticing Y/N’s habits. The exhaustion. The untouched dining-hall meals. The same worn-out backpack. The way Y/N always says they’re “fine.” And eventually, they start realizing that Y/N isn’t just the quiet student who’s always studying. They’re someone desperately trying to hold onto the only opportunity they’ve ever been given.
Y/N has always lived under strict rules. Their parents control where they go, who they see, and almost every part of their life. When Y/N becomes friends with Riley, Maya, Lucas, and Farkle, they finally experience what it’s like to have freedom and people who genuinely care about them. But when Y/N’s parents discover how close they’ve become to the group, they decide to pull Y/N out of school and cut off their friendships. Now Y/N must find the courage to speak up for themself while their friends try to support them through it.
Y/N has spent her entire life with a mother who never wanted to talk about her father. Growing up in a difficult home, she finds comfort in the one thing she truly loves: engineering. After skipping two grades because of her intelligence, Y/N ends up in Peter Parker’s class and joins the school’s robotics club. Peter quickly notices something strange about her. The way she thinks, her sarcasm, her mannerisms, and especially her natural talent for engineering all remind him of someone he knows very well—Tony Stark. When Peter casually points out the similarities to Tony, Tony initially brushes them off as coincidence. But after finally seeing Y/N for himself, the similarities become impossible to ignore. Neither Tony nor Y/N knows the truth. The brilliant girl Tony thinks is simply an unusually talented student is actually his daughter—the child he never knew he had.
Y/N moves to New York after discovering they have a half-sibling they’ve never met. Suddenly becoming part of the Matthews and Hart families, Y/N struggles to adjust while keeping their past private. As they grow closer to their unexpected sibling and the rest of the group, family secrets begin to surface, forcing Y/N to decide whether they’re ready to trust the family they never knew they had.
After an unexpected situation leaves Y/N without a comfortable place to stay, Cory and Topanga become their temporary guardians. Y/N moves into the Matthews household but struggles to accept their help, keeping everyone at a distance and insisting they won’t be staying for long. As Riley welcomes them like family, Maya understands their walls, Shawn recognizes their guarded nature, and Cory and Topanga slowly earn their trust. Over time, Y/N begins to realize that the Matthews home might be more than just a temporary place to stay—it might finally be a home.
