Battle Hearts This Military x Doctor AU was inspired by one of my wonderful readers, Lezza. 💛 I hope you enjoy this journey as much as I loved creating it. Joong and Dunk have been married for years-a quiet, steady kind of love built on routines, inside jokes, late-night dinners, and knowing each other better than anyone else. Their marriage isn't perfect. It's real. Joong serves in the military. Dunk is a doctor. Both have dedicated their lives to helping others, but their jobs come with sacrifices neither of them can control. When Joong receives orders for a high-risk deployment, their world changes overnight. Six months. No communication. No promises except the hope of coming home. As distance grows and uncertainty settles in, both men are forced to face fears they've spent years avoiding. Because sometimes the hardest battles aren't fought on the front lines. Sometimes they're fought in silence. In waiting. In loving someone when every day comes with the possibility of loss. Battle Hearts is a story about love, sacrifice, resilience, and the people who keep choosing each other even when life makes it difficult. Not because love is perfect. But because some people are worth fighting for.

Dunk spent so long proving his love to someone who refused to accept it. So one day, he stopped. But when the chase ends, the one who always said no is the one who can't stand the emptiness. Anger erupts-not because he doesn't care, but because he cares too much.

It was just a dare. Just one kiss. Just one night. Joong still calls himself straight. Dunk still pretends it meant nothing. But nothing doesn't come with jealousy, late-night touches and the kind of tension that ruins friendships. Friends with benefits was supposed to be easy. Catching feelings wasn't part of the deal.

Joong used to have a girlfriend. Dunk used to have a best friend. Now, neither of them have what they once did. After a messy breakup, Joong is surrounded by friends trying to cheer him up-but there's only one person who can make him smile like he used to: Dunk, the best friend he pushed away without a word. When Dunk shows up, there's tension, there's silence... and then, there's understanding. They may have drifted, but the bond never really broke. Then Joong proposes something insane: Let my ex think I've moved on-with you. Let her regret leaving. It's a wild plan, but Dunk agrees. Not because he wants to help Joong win his ex back-but because Dunk's been hiding burning desires he's never had the space to explore. And this might be the one chance to finally understand them-with someone he trusts. Even after getting back what both of them wanted,fate finds their way back to each other,tangled in confusion and desire. It was supposed to be a trade. A way to get back what they lost. But somewhere between blurred lines and late-night confessions,sweaty bodies tangled together, the question isn't who they want to fool- It's what they're starting to feel. Love, lust, and loyalty-this isn't just a fake plan. It's something real they never saw coming.

"Fucking... asshole..." Dunk cursed under his breath, his body trembling from the overwhelming sensations. Joong leaned in, voice low and vicious against his ear. "That's right," Joong growled, his hips snapping forward, thrusting into Dunk with increasing force. "I am fucking an asshole." For generations, the Boonpraserts and Aydins have stood side by side-two of Thailand's most powerful dynasties, bound by legacy, empire, and an unspoken promise to protect each other's interests. Now, that promise is becoming permanent through the upcoming marriage between the Aydin heir and the Boonpraserts' only daughter. Joong Archen Aydin is everything an heir should be: elegant, obedient, and impossibly perfect-the golden son shaped by legacy and expectation. Dunk Boonprasert, on the other hand, is chaos incarnate. Reckless. Sharp-tongued. The black sheep his family tries to hide behind polished smiles and public image. The two have been enemies since childhood-locked in a lifelong war of petty sabotage, brutal words, and fights that always turned ugly. But everything changes the night Dunk decides to give in to a moment's vulnerability and sleeps with Joong. His sister's fiancé. His lifelong nemesis. The one person he should have never touched.

This is the world where human's race faces near extinction. Dunk Natachai, who is still a human, faces a difficult situation when he encounters the other human's species, they call it; the creatures, when he wants to search for the missing of his other human friends. That creature whose strength is ten times stronger than a human can be, captures him, locks him in a dungeon, but doesn't let him die or transform him into another creature. The reason? It is all because Dunk Natachai is immune to them. And the creature definitely needs something from his body for his own survival. [this will be 21+, MINOR DNI]
