kim gun-woo as your boxing coach × you (female trainee) headcanons 🥊💕
omg guys i am actually unwell over this concept… like imagine having kim gun-woo as your personal boxing coach?? the quiet, insanely hot, abs-for-days man who barely talks but looks at you like he’d go to war for you?? i had to write these headcanons immediately because my brain won’t shut up about it:
• he barely says full sentences when he’s correcting your form (“elbow up.” “breathe.” “again.”) but the SECOND any other guy in the gym even glances at you too long, he’s suddenly standing right behind you like your own personal 6ft silent bodyguard. zero guys breathe in your direction when he’s around, it’s actually hilarious
• acts like you’re just another fighter but always sets aside the newest, cleanest gloves for you. after a super rough session when you’re literally dying on the mat, he just drops his own towel (still warm from his shoulders) over your head and ruffles your hair once before walking away like he didn’t just do the cutest thing ever 🥹
• those late night trainings when the gym is empty and the lights are low?? it’s just you two, the sound of gloves hitting pads, and heavy breathing. that’s when he actually starts opening up… quiet stories about why he fights, what he’s lost, what he’s protecting. my heart literally aches for this man btw
• gets SO much quieter and intense when you start sparring with the guys. one time a partner gets a little too rough with you and gun-woo steps in immediately, voice all low and dangerous: “she’s done. with me.” the dude basically evaporates on the spot
• his hands are so careful when he’s taping yours or fixing your stance… calloused but warm and steady. you keep catching him staring at the back of your neck or your jaw when he thinks you’re not looking, then he clears his throat and barks another command like nothing happened
• on your bad days when you’re feeling too small or not strong enough, he corners you after practice (both of you sweaty and tired) and says in that deep calm voice, “you’re mine. my fighter. means you don’t get to doubt yourself. understand?” …the “mine” just hangs there and he doesn’t even take it back
• after your first real fight he’s waiting outside the locker room with two cold sports drinks. doesn’t say much, just gently bumps his bottle against yours but the look in his eyes (proud + protective + a little possessive) says everythinggg
• the almost-kiss happened after a brutal training day. you’re both leaning on the ropes breathing hard, he reaches up to wipe sweat off your cheek with his thumb… and you both just freeze. dead silence for like three seconds before he pulls back, jaw tight, and mutters “shower. now.” like he doesn’t trust himself to stay near you
• random sweet things: new wraps magically appear in your bag, your favorite post-workout snack is always in the fridge, he somehow knows exactly how you like your coffee/tea and leaves it for you without saying anything
• he won’t say he likes you for the longest time but after a big win, adrenaline still pumping, he pulls you into a back hug outside the venue, buries his face in your sweaty hair and whispers, “you scared the hell out of me today… don’t do that again.” that’s basically a full love confession from gun-woo lmao
Can someone write the full fic immediately pls i’m begging 😭
