Y/N Byers, Will’s twin sister, has been part of the Hawkins chaos from the very beginning. Starting at Season 5, she’s caught between protecting her brother—who’s quietly in love with Mike—and her own growing feelings for Mike after years of closeness and secret flirting. With Steve and Robin acting as her overprotective older siblings and the Upside Down returning stronger than ever, Y/N must navigate danger, loyalty, and a love she never meant to have.
Y/N knows nothing about hockey—except that their friends love the Montreal Canadiens and somehow scored rinkside seats. What starts as a night of confusion and cold air turns into lingering eye contact with Shane Hollander, a player who notices Y/N just as quickly as they notice him. By the end of the second period, a towel and a phone number prove some games don’t stay on the ice.
The Tower was unusually quiet—at least, quiet by Avenger standards. Y/N was barefoot in the common kitchen, standing on her toes to reach the top shelf while the coffee machine hissed aggressively behind her. Someone—Tony—had replaced the regular mugs with novelty ones again. She grabbed the least offensive option (World’s Best Billionaire, unfortunately) and poured coffee like her life depended on it. “Careful,” Natasha’s voice came from behind her. “That thing bites before 8 a.m.” Y/N snort
Graduation day finally arrives in Hawkins. While Steve coaches one last middle school baseball game before the ceremony, Y/N—Dustin Henderson’s older sister and Steve’s wife—watches the kids she helped raise step into their future. Four months pregnant and surrounded by family forged through monsters and survival, she learns that after the Upside Down, life doesn’t just go on—it grows.
