Ten years into a zombie apocalypse, Katsuki and Kirishima have survived by building an unspoken, physically intimate bond rooted in trust, routine, and necessity. When they encounter Y/N—the first woman they’ve seen in years—her presence disrupts not only their survival dynamic, but the fragile, undefined connection between them, forcing all three to confront feelings that can no longer remain unacknowledged.
Katsuki shocks his entire friend group when he shows up with a girlfriend no one knew existed—only making it worse when they realize he’s been living with her for years while they’ve regularly been in his apartment.
At twenty-five, Katsuki is one of Japan’s most desired heroes and somehow the biggest loser in romance imaginable. He’s never kissed anyone, never dated, and has absolutely no clue what he’s doing once he actually likes somebody. Unfortunately for him, y/n is the first person who sees Katsuki instead of Dynamight—and now this terrifying pro hero can barely survive a casual conversation without internally combusting.
Katsuki Bakugou owns half of Tokyo — including the restaurant where she works. She’s just a waitress. He’s the most dangerous man in the city. What begins as curiosity turns into obsession, and when he decides she’s the only woman he wants, he cuts off the rest without hesitation.
Katsuki’s greatest joy in life is tormenting his teenage sons. From randomly smacking the backs of their heads to silently appearing behind them like a sleep paralysis demon, he treats parenting like a full-time comedy routine. Unfortunately for him, both boys inherited his personality—meaning the Bakugou household has become an endless cycle of screaming, wrestling, revenge plots, and the boys physically jumping their father whenever he gets too annoying.
After leaving an abusive marriage that he didn’t recognize until it was too late, Katsuki Bakugou rebuilds his life with more awareness, more control, and stricter boundaries than ever before. Years later, through Kirishima, he meets someone entirely different—steady, genuine, and safe—and for the first time, he understands what love is supposed to feel like.
A delusional sidekick pushes too far, mistaking Katsuki’s respect for interest—until she crosses a line that forces him to make one thing painfully clear: his wife was never replaceable.
Katsuki Bakugou, 28 and Japan’s No. 2 Hero, is scarred, tough, and blunt to everyone except his wife. With Y/n, he’s soft, protective, and secretly obsessed with starting a family. Beneath the attitude, he’s just a devoted husband with intense baby fever.
After Katsuki calls her clingy, Y/N gives him the space he asked for—but the distance that follows makes him realize just how much he misses her warmth. As she keeps her distance, Katsuki is forced to confront something he never expected: he actually likes when she clings to him.
Katsuki Bakugou is a top pro hero in his thirties, married to the woman who softened him just enough to survive domestic life. Their fifteen-year-old son, Ryu, inherited his father’s explosive quirk and his mother’s sharp stare—but none of the enthusiasm for being compared to Dynamight. Ryu isn’t angsty or troubled; he’s just fifteen, permanently unimpressed, and mildly allergic to authority—especially when it comes from his own dad.
At a yearly barbarian festival where men must court their chosen partners, Katsuki becomes fixated on y/n—a woman who refuses every suitor. Forced out of his usual confidence, he awkwardly begins trying to win her over, with Kirishima cheering him on as he navigates unfamiliar ground.
A heated argument between Katsuki and Eijirou escalates when concern turns into confrontation, forcing both of them to face the one thing they struggle with most—admitting how much they actually care about each other. All while y/n is stuck to calm things down.
They’re just friends. That’s what everyone thinks. But Katsuki’s hands are always on her—on her shoulder, her sleeve, the small of her back—like he needs the reminder that she’s still there. And the longer she stays in his apartment, in his routine, in his space, the harder it gets to pretend it’s just habit.
Three Japanese pro heroes arrive in America for a short conference, only to get stranded for two weeks due to a flight delay. Assigned a local hero to guide them, they expect structure and professionalism—but instead get someone reckless, unfiltered, and completely unimpressed by them. As she drags them through the city, drives like she has something to prove, and refuses to treat them like legends, the three find themselves drawn in—each in their own way—turning a temporary inconvenience into something far more complicated.
Katsuki agrees to a casual date expecting nothing special—only to be completely thrown off when Y/N shows up looking far better than her pictures. Annoyed, intrigued, and lowkey territorial, he realizes too late that he didn’t get catfished… he just underestimated her.
As graduation approaches, the cracks in Katsuki and Y/N’s carefully hidden relationship begin to show. With the dorms disappearing and real life closing in, pretending to hate each other becomes harder than ever—but walking away was never an option.
Y/n and Katsuki Bakugou aren’t together anymore, but somehow they’ve built the softest, most chaotic little family with their three-year-old son, Akio. Katsuki has Akio on the weekends and Y/n during the week, but they talk constantly—sending pictures, videos, and late-night calls just to keep up with their toddler’s every moment. They hang out more than they should, laugh more than exes usually do, and slip into routines that look suspiciously like a relationship they “don’t have.”
Katsuki Bakugou is engaged to another woman, but inviting Y/N to the wedding forces old feelings back to the surface. Their breakup was never about lack of love—only terrible timing—and now they’re trapped inside the same friend group pretending they’ve both moved on. Meanwhile, Y/N grows closer to Shoto Todoroki, her former fling and current best friend, which slowly pushes Katsuki toward a breaking point.
Katsuki realizes three months into his relationship with Ochako that, despite everything being “right,” his feelings aren’t there. When a new coworker, y/n, unknowingly sparks something real, he refuses to stay in something forced—ending things cleanly and finally acting on what actually feels genuine.
At Izuku Midoriya and Ochako Uraraka’s wedding, a simple bouquet toss turns into something bigger when y/n catches it—and the entire room immediately looks at Katsuki. What starts as a teasing moment shifts into something more real, as he stops brushing things off and starts leaning into what’s already there. The story follows that quiet progression between them—subtle, unspoken, and certain—until it builds into something undeniable… and eventually, something permanent.
Katsuki didn’t expect to get pulled into a flirty back-and-forth with Best Jeanist’s adoptive daughter—but he definitely didn’t expect to enjoy it. As their teasing turns mutual, both Jeanist and Edgeshot start watching him like a threat. Unfortunately for them, Katsuki isn’t backing down. And now it’s less about surviving them—and more about winning her.
After the war, Y/N chooses a quiet life in America instead of the hero path, leaving behind the boy who never confessed his feelings. Years later, she returns to Japan for a Class 1-A celebration, completely unaware that Katsuki has spent all this time quietly comparing everyone else to her. Now face to face again, he’s forced to confront the feelings he never let himself have.
Y/n never meant to drift away from him — it just happened. One moment they were kids sharing dreams under the same stars, and the next, Katsuki Bakugou was on every news channel, a rising pro hero. And y/n? She was nowhere to be found.
At twenty-five, Pro Hero Dynamight is sharp-tongued, explosive, and carefully controlled—until a night of drinking with friends leads to one unfiltered comment about Y/N going viral. Forced to face the consequences of his honesty, Katsuki Bakugou learns that some truths, once spoken, can’t be taken back—and maybe shouldn’t be.
