"Spare me! Please!"

A blood-curdling scream fills the empty gym room as Jongin lifts Yun's heavy right leg up to the same level as his shoulders, then pushes it down towards Yun's stomach fat, squishing it between her thigh and chest.

"I think I just pulled a muscle!" a voice vaguely resembling Lee Yun shrieks in agony.

"You don't even have muscles!" Jongin replies sharply, beads of sweat decorating his handsome face as he attempts to push the limb in his hand down as far as it can go. The pair were currently in the middle of their first workout session - leg stretches essential to the beginner dancer.

"I do so!" the indignant girl kicks at him blindly, landing a lucky hit near her trainer's beautiful jaw line.

"OUCH!" a string of profanities spew out of his mouth, "You're lucky my jaw isn't shaped by plastic and botox, or else that kick would have cost you enough to keep you in dept for the rest of your life!"

"Let me go!!"

"Never!"

"LET ME GO!!!"

"STAY STILL!"

Yun bites back angry tears, feeling the intense pain of the mid air leg split violently ripple again and again through her calves and thighs. The violent scene was indeed Lee Yun's very first class with mister Kim. After merely half an hour, Yun can only use one word for the devil currently forcing her body into impossible positions: strict.

When Jongin had led the excited student into the private room in SM building filled with exercising equipment, Yun had been full of joy and anticipation. 

Jongin had firstly looked towards the treadmill, but then shook his head silently to himself. Next, he moved onto the rowers, but took one glance at her bloated stomach, and gave a tiny sigh. After repeating the same pattern for three other machines in the room, he settled upon the ultimate training device: himself.

But was he by far the worst choice out of all the sophisticated machinery in the room...

After 30 minutes in the room, the girl was already at her limit and wishing for death to come quickly.

"Faster! Move your legs one after the other! Come on! I want to see you sweating! Move move move!!!"

"I can't...anymore...seriously..." Yun pants ungracefully as her trainer put the treadmill speed up another notch, "stop please!...I need...a rest!"

"Nope, 2 minutes and 49 seconds to go!" Jongin slaps her hand mercilessly away as it attempts to clutch onto his arm in desperation, "2 minutes and 45 seconds now! Come on come on!"

A happy smile tugs at the dancer's lips as he watches his new student persevere with the treadmill. Honestly, she's only been running for 10 minutes and she's already sweating buckets... he frowns a little to himself, how on earth will she be able to dance for 3 hours when we move to the studio next week?!

"And...stop!" Jongin command as the timer beeps loudly. Gradually slowing the machine down to a walking speed, he helps Yun down as she struggles to stand on her own feet after the demanding workout.

"Jongin...I weight 96 kilograms...please...don't train me like you would train yourself..." she slumps into his arms, completely drained from the running session.

The trainer tries, but quickly fails to hold in a mocking laugh, "If I were training you the way I train myself, the duration of that stretch exercise and the intensity of that treadmill workout just then probably would have killed you on the spot. You should be thanking me for shortening the duration."

"How nice of you, I feel like I'm dying anyway," she mutters the last part under her breath.

"Are you ready for some basic moves? We can start with a kick-cross-step for today."

"...Do I look like I'm ready for some 'basic moves' at the moment?" Yun glares daggers at the grinning boy, "I don't even think I'll be able to walk properly for the next week or so."

Concerned, Jongin bends down to her legs, and starts rubbing her thighs with both hands, "This will help, trust me. Luhan begs me to do it for him after practice all the time--"

"No!" Yun quickly retreats her leg, a blush adding to her already red face, "I can do it myself."

"Don't be ridiculous!" he makes a grab at her thighs again, but she avoids his hands with surprising dexterity, "Yun, why are you being so difficult?"

"My thighs..." she mumbles almost unintelligibly, "the fat will wobble if you rub it like that..."

Jongin mentally slaps himself for being so ignorant and careless as he glances worriedly up at the girl's face from his position on the floor. To his silent horror, he finds her eyes clouding with embarrassed tears, teeth biting onto lower lip to hold in the last of her dignity.

Kim Jongin why must you be such a blockhead?! Can't you at least try to understand the difficulties of being fat?! plump lips sigh in defeat, Baekhyun would definitely understand her in this sort of situation...

"Yah!" a short male makes his way towards the two just almost at the same time his name passes through Jongin's thoughts, "You bastard, did you make her cry again?!"

Jongin gulps nervously, remembering Kris' punch the last time he had insulted Yun.

With visible effort, Yun blinks her tears away rapidly before Baekhyun reaches them in the private gym room, and forces a smile onto her lips as she greets him,

"Hey Baek! Have you all just finished training?" she eyes Kyungsoo, Suho, Chen and Luhan who were all coming into the room, following behind Baekhyun.

"No, it's just the vocalists today who had to finish recording MAMA," his voice is kind and reassuring as he speaks to Yun, "the rest are at home sleeping because they had their practice until late last night." Baekhyun turns to glare at Jongin suspiciously, immediately switching his tone of voice into one of plain distaste, "Did you or did you not make her cry?"

"He didn't," Yun squeezes his arm tenderly, reassuring her friend, but at the same time bothering Jongin a little with the intimacy of the gesture.

Wait, are those two going out or something? Jongin suddenly questions, but then realises that the answer shouldn't matter to him either way. Well...not that it really has anything to do with me I guess...

"He better not have," Baekhyun mutters, before turning his back to Jongin and directing his full attention to Yun, "I missed you! Did you have a good exercise session?"

"Yes it was wonderful," Yun struggles to keep the sarcasm out of her tone, "Jongin is an amazing trainer."

"I'll bet he is," Luhan winks at her playfully, causing another small, uncertain voice at the back of Jongin's mind to wonder if Yun was flirting with every other EXO member - apart from himself.

What's wrong with me? he shakes his head slightly to clear the confusing feelings and odd reactions, Yun can flirt with anyone she wants, why should that concern me?

"Kai...I need to thank you," Baekhyun speaks up, breaking the younger out of his odd thoughts.  "if Yun says you're a good trainer, then I'll believe her and entrust her to you completely." He smiles at Jongin almost begrudgingly, but sincerely and gratefully.

"Stop pretending to be her dad," Jongin cracks a smile, punching his arm lightly in uncertain friendship, "you're a good guy, Baek, but you really need to stop being such a nag."

"You're actually not so bad yourself Kai, I'm starting to like you more, now that you're sincerely trying to help my friend."

"Call me Jongin," he extends his hand out for Baekhyun to shake, surprising everyone except Yun, who smiles in encouragement, "all my friends do."
