Author’s Note: Hi sweetie!! Wow, this got out of hand and kinda turned into a whole ass fic T___T Anyway, thanks for the request! I had fun writing this, so I hope you enjoy it as well. It’s my first time writing a LOL/ HEARTSTEEL story (although I have some things in the drafts), so I’m a little nervous… Let me know what you think – as usual, my asks are always open! 💜

‘I’ve never seen you this excited about exercising,’ Sett chuckled, when you quickly unbuckled yourself and jumped out of the car.
‘It’s not that I am in a hurry to break a sweat… It’s just best that I get inside the gym before I chicken out!’ You replied, opening the door to get your sports bag out from the backseat.
‘Are you still nervous? I told you it’s not that scary. And even if it is, I’ll be right there with you.’
You knew that. Frankly, if he wasn’t coming along with you, there’d be no way for you to force yourself and do it on your own. After the last experience you had, even the mere thought of going to the gym was unpleasant.
Although you were never thin, you were fine with how you looked, until the work stress got to you so much that you’d gained a little too much weight. It was obvious that it affected you in not so positive ways – you felt tired all the time and stressed about it, which made you binge eat all of the snacks you could find. This was not a healthy coping mechanism, so you really wanted to break yourself out of it and get back on track with a healthier lifestyle. Your primary goal was not about the numbers on the scales, it was to feel good about yourself again and become more active in general.
But the personal trainer you started working out with several months ago just… had a very peculiar approach. Every time you were on your way to the gym you felt weak in the knees from the desire to drop to the ground instead of entering the building. It was like boot camp with him. He would yell at you when you didn’t show enough effort, tell you that your sides would hang down to your ankles if you continued like this, called you flimsy and unmotivated.
Which only made you even more unmotivated and self-conscious. To the point that you decided to stop going to the gym altogether to stop the constant humiliation.
But just a couple months after that, you met Sett. The tall frame and fluffy head of hair hidden underneath a cute beanie with cat ears drew you in at first. And ultimately, the warmth of his character and the love for his family made you give that himbo-looking man a chance.
And since your boyfriend was a complete gym rat, enjoying his workouts almost on the daily, you shared your past experiences with him.
‘What? That fucking sucks, muffins.’
Oh yes, he also loved nicknaming you after all kinds of foods and flavors. You thought he was teasing you at first, but if the earnest look in his eyes was any indication, he was serious about displaying his affection like this. He did not allow himself too many sweet things, while he did have a sweet tooth. Maybe using them as your nicknames was his subconscious effort to make it a little easier for him? You’d never know.
‘What was that guy’s name, by the way? Not that I plan on doing anything…’ He asked you then, narrowing his eyes.
He was most definitely planning on doing something.
‘It doesn’t matter,’ you sighed. ‘I just know how much you love working out, and I wish I could support you in that too.’
He blew a strand of his brightly colored hair out of his face and placed his wide palm over your hand.
‘What if I support you in this?’
And so, he invited you to come train with him at his local gym. He promised to look after you there and help you find ways to enjoy your workouts.
‘Don’t stress about shit, I got you. Working out is fun, and I’d happily be the one to teach you all about it!’
His excitement countered your resistance, and in the end, he had convinced you to give it a try. You decided to get some new workout clothes as well – to start completely anew. Sett also surprised you the day before Day X by giving you a pair of matching workout sneakers as a gift.
‘Everyone should know these sweet cheeks are taken.’ He told you, and yelped as you pinched his huge bicep in response.
So today you were in a rush to go try your new sneakers and clothes on, and get back into working out! That is, until you reached the front door of the building and saw your reflection in the glass door. Sett picked up your hesitation, opened the door and subtly grabbed your free hand while holding it open.
‘Let’s go, butter cookie.’
He did not let go of your hand until he delivered you to the female changing room.
‘Go change and I’ll pick you up from here.’
You felt like a child, who couldn’t do anything alone, but you nodded, putting on your big girl pants. Taking your sweet time to change, you almost decided to slip out through the window, but then the sneakers caught your attention. As you held them in your hands, you thought of how happy Sett was when you agreed to come here with him. He even went shopping with you, which wasn’t at all his favorite pastime. You had to give it a try, at least for him. And for yourself, actually!
When you finally walked out of the changing room, looking like a pro fitness maniac in your new sports attire, your boyfriend was already there.
‘I thought you sneaked out the window or something,’ he chuckled, and your eyes went wide, because… How did he know?
‘Let’s go,’ you mumbled, and he took your hand again, squeezing it reassuringly.
It was not the busiest time at the gym, and you were thankful for Sett’s consideration of your comfort. He missed the opportunity to overlap with his gym bros just to make it slightly less stressful for you.
‘Since you hate running, why don’t you use the elliptical machine to warm up? Just ten minutes, slowly increase up to level 5 or 6. And watch your heart rate, just like I told you, okay?’
‘Yes, boss.’
‘Good.’
The pleased look on his face gave you an energy boost, so you were growing a bit more enthusiastic with every resistance level added on your machine. It was getting a little tough by the end of your 10-minute session, but when you turned around to see Sett doing some decent running on the treadmill behind you (which made the floor underneath you shake), you felt a tinge of competitiveness in you.
Of course, it was silly for you to actually try to beat him at this – the stamina and body composition was extremely different between the two of you. But now you wanted to keep up with him at all costs, even if in your own way.
Sett approached every new machine or exercise slowly, carefully giving you instructions and making sure that you did not overdo it and hurt yourself in the process. He also made sure to tell you how awesome you were doing, although you were certain that no one else in that gym was impressed when you did bicep curls with 1.5kg dumbbells.
Well, at least you had a large boyfriend to compensate for your lack of strength. It was impressive how much weight he could pull, even though it was kind of expected from a man in such a great shape. You were jealous of yourself for snatching this highly disciplined goofball. Working out with him was not at all stressful, and even with the tiny achievements you’d made, you felt like it was an enjoyable experience.
‘Good job, five more,’ he announced, when you were doing your last rounds at the pull-down machine.
With sweat rolling down your spine and your hands up in the air, you noticed someone glancing at you from the side. It felt a bit odd, so you had to pause for a second to get back into your workout flow. Sett noticed your momentary discouragement, and stepped in front of you, utilizing his massive build to seal you off from the world.
‘Concentrate on using your muscles and pulling the bar down through the burn. I will count. Five, four… Yes, good!’ He helped you finish your routine and let you rest for half a minute.
‘Wow. You are sexy when you’re so focused on your exercise, ice cream cake. I might regret bringing you here for all to see,’ he told you, crossing his arms over his chest, and you shushed him in embarrassment.
Not that it didn’t stroke your ego just a wee bit. But his tone quickly changed back into his trainer mode.
‘Now, move your butt, we gotta get to those bikes while they’re free. You didn’t think I’d let you go home without a cool-off?’
With a capricious whine, you let this naughty man drag you to the next machine. But in reality, you were not opposed to spending another 10-minutes showing off your couples sneakers and successfully finalizing your first workout together. With the feedback you were getting from your new personal trainer… You could get used to this.
