[kirishima] not for others -

- fluff , body positivity ,
[weight , muscle gain , calories / macros mention ]

"eiji you ready?" you knock on the redhead's door as you fix the sweat band on your wrist. "yeah! coming" he responds. moments later he appears in front of you in one of your tank tops. "sorry, i didn't do laundry" he flashes a sheepish smile.

"looks better on you than it does on me anyway" you chuckle, running your hand through his unstyled hair. you think he looks cute with his hair down like this but he insists he doesn't look 'nearly as cool and manly'

kirishima frowns at your comment but brushes it off because you two always make jokes like that. you both walk up to aizawa sensei for permission to use the gym before heading there.

you chug down the last of your pre work out kiri had prepared for you as you walk hand in hand.

"let's do some cardio and sparring practice after?" you suggest as your boyfriend stretches and warms up. "sure baby!" he agrees, nodding giddily.

you both start your cardio routine, push ups, high knees, running, occasionally making small. you had been feeling bad about your body. after a few months of muscle building you were now stuck in your plateau phase. results started showing up a lot slower and you're exhausted.

you started your journey for yourself, to be stronger for yourself but as you go down the fitness rabbit hole you quickly started comparing yourself to others and only be happy when you get the validation you want.

you decided to push yourself further with today's cardio, doing 8 sets instead of your usual 4. kiri notices this but figured it was just you making full use of the pre workout shake you had. "hey babe? i'm gonna go on with sparring we can practice together once you're done" he says rather hastily.

you pant as you push yourself to finish the last set of your push ups, loud music filling the atmosphere. kiri was in charge of music for today and he always put on the best beats to go beast mode on.

you didn't get nearly as much carbs in you today and you knew you weren't going to have enough energy to push through for longer. you had been so busy with school work that your diet's messed up. you no longer ate according to your macros but you didn't want to stop with the work outs.

you had to keep going if you wanted to keep up with the other guys, if you wanted to see results, if you wanted others to notice your growth. sweat drips from your chin as you stayed in a plank position, panting as you struggle to breathe.

"y/n..you done with cardio?" kiri walks up to you with a clear worry in his expression. "you don't look too swell" he says, crouching down in front of you, holding your chin up to look at him. your face was pale and cold sweat making hair stick all over your face.

he leans in and places a quick peck on your lips, smiling sweetly.

"i'm f..fine kiri, come on we gotta spar" you brush him off with a weak smirk as you pick yourself up from off the floor. your vision was hazy and the room was slightly spinning but you pushed through. "this is nothing, i can go further" you convince yourself as you lead yourself to the sparring stage.

a faint ringing in your ear distracts you from the punch kiri was throwing your way but you manage to dodge it at the last second. your head felt light as you swerve your body as best as you could to avoid your boyfriend's attacks, you throw a quick false uppercut which he dodged with ease.

you throw a kick his way but missed him completely which made you lose balance. "don't mind" he encourages you as he helps you up.
"baby i really think you should get some rest." his arm around your waist, holding you up. "no, no i can keep going eiji. let's restart. please?" you try to reason with him before feeling the room spin around you.

you stood up straight for a moment before falling to your knees again, you felt disoriented and out of control with your surroundings. your legs shaked from fatigue as you let out an annoyed groan.

"why the fuck am i so weak? you grumble, rubbing your aching temples.

kirishima shoots you a quick glare before letting out a sigh. "no, i'm bringing you back to your room." his voice stern as he picks you up, carrying you over his shoulder. your arms betray you as they fall straight down.

despite your best efforts to resist, the stronger male kept you in place with his arm wrapped around your legs.

your heart was now beating at a rapid pace as if it was threatening to give out at any given moment. kiri stayed silent as he picks you two bags' up.

"i'm sorry" you sigh into his shoulder. "for?"—"for cutting our practice short" he didn't say anything, walking out to the gym. he didn't look too happy either and you thought he was disappointed in you for being weak.

"what's wrong with him?" aizawa sensei stops your boyfriend in his tracks. "i'm fine sense-" "his body's shutting down." kiri cuts you off.

he's right. you were shutting down. you didn't have enough fuel for the labor you were putting your body into.

aizawa sensei tells him to get you in bed before walking off yawning. "get some rest y/n. take the day off tomorrow if you need to."

"i'm going to tell you something once i get you in bed and you better listen to me. do i make myself clear?" you gulp as you nod. you knew you had pushed your luck with him this time. he doesn't play around when it comes to you and your wellbeing and you were very aware of this.

he puts you in bed, taking your shirt off. he puts the bags down and turns the ac on. he grabs a chair and sets it next to you before sitting in it. "you're overworking yourself and i know you aren't getting your macros in y/n so don't try lying about that." his usual cheery attitude was gone and he was instead stern with every word he spoke.

you turn your head to avoid his gaze as you pull the sheets up to cover your body. kiri sighs as he hops into the space next to you, holding you closer into his body. "baby you have to stop being so hard on yourself." his voice was now a little more comforting.

you hated it when kiri scolds you and it doesn't help you feel better when he does. you know he's just looking out for you but you still hate having him mad at you.

his hand patting your head softly, pushing out strands of hair sticking on your face. "i'm sorry" your voice small. "what are you sorry for, answer correctly this time."—"i'm sorry for overworking myself." "and?" "and not feeding my body correctly."

he lets out a sigh and nods. "it's going to be okay" he hums as his hand caresses your side.

"i know somewhere along the way your motives changed and i'm not going to blame you for it but as long as you keep doing things for the sake of others, you will never be happy." "but-" "i'm not finished. your journey is supposed to be something fun. not a chore. you're perfect as is y/n, please believe me when i say that. if you want to know what i think, i think you should only change for yourself, not for others."

you were quiet. your motives did change. and the moment it did, everything got harder for you. "i love you for who you are, period. i'll continue loving you through all the changes you make for yourself. but i don't want to see you in pain." you hold onto his arm, hugging it as he envelopes you with his body with a hug.

your boyfriend's gaze on you soften as you stayed in his embrace, legs on top of each other.

"help me start over and do things right"

he kisses the top of your head as he giggles. "anything for my baby."
