Y/N, a twenty-three-year-old living in Florida, unexpectedly becomes the digital pen pal of elite hero Katsuki Bakugou after the two continuously match on a Duolingo leaderboard. What begins as a competitive streak over Spanish XP deepens into something far more intimate when Bakugou shows genuine, visible concern over Y/N's four-day absence during a cruise, eventually leading to vacation photos being sent directly to his phone. This online connection becomes a volatile problem, however, because Bakugou is already engaged to Yuki Haruno—a master of weaponized softness who maintains a pristine, porcelain-doll facade. Aware that Y/N knows about their engagement and "would love to meet," and facing Bakugou's casual willingness to take a trip down to Florida, Yuki's sweet exterior hides a brewing, calculated war to protect her domain against the unsuspecting Y/N.
Y/N is living her dream life: successful Support Course graduate, proud owner of a Porsche 911, best friends with Camie Utsushimi, and the undisputed biggest Dynamight fan in Japan. So when Camie drags her to a club one Friday night, Y/N expects drinks, bad decisions, and maybe a hangover. She does not expect to spend the evening flirting with a rude blonde stranger who seems personally offended by her existence. In her defense, the lighting is terrible. Also, heroes look different in person. Also, he's drunk. Very drunk. What starts as harmless banter turns into an entire night of arguing, flirting, and Y/N passionately explaining why Dynamight is the greatest hero alive—to Dynamight himself. The next morning, Y/N discovers the man she spent all night teasing, insulting, and accidentally psychoanalyzing was none other than Pro Hero Bakugou Katsuki. Even worse? He has her number. Now Y/N is stuck navigating a friendship with her celebrity crush while pretending she doesn't have an entire shelf dedicated to his merchandise. Meanwhile, Bakugou finds himself increasingly attached to the one fan who treats him like a normal person—and is somehow completely oblivious to the fact that he's flirting with her. With Camie stirring the pot, embarrassing text messages piling up, and a growing attraction neither of them knows how to handle, Y/N and Bakugou are about to learn that falling in love is a lot harder than fighting villains. Especially when everyone else figured it out months ago.
