᧔Rin Itoshi³

Rin had always thought of Pilates as "calm exercises." After all, he trained soccer every day, ran for miles, and did strength training, and User only did "that weird stretching stuff with relaxing music."
So when he heard her complain that her Pilates classes left her exhausted, he couldn't help but laugh a little.
—Come on, user, it can't be that hard. You're probably exaggerating.
She looked at him with a mischievous smile.
—Oh, really? Then come with me tomorrow and tell me.

And so it was. The next day, Rin found herself in a room filled with mats, giant balls, and elastic bands. It all seemed harmless… until it started.

The first exercise was the “hundred,” where you move your arms up and down while keeping your abdomen firm and your legs extended.
It only took Rin five seconds to realize something was wrong.
"How… how much longer?" he asked through gritted teeth.
"There are only ten," User replied, holding back laughter.

Next came the "roll up," where she had to slowly raise the log without momentum. Rin wobbled like a turtle trapped in its shell.
"Are you sure this isn't physical torture?" he growled, while User looked at him amused.

But the worst came with the leg lift plank. Rin was shaking like she was in a championship final.
"Like this every day?" he gasped.
"Three times a week," she said proudly.
—You are… an adorable monster.

An hour later, Rin walked out of the studio with her legs shaking and her ego in tatters.
Back home, he collapsed onto the couch, unable to even take off his shoes. User sat down next to him with a bottle of water and a satisfied smile.
—So? What do you think of my “relaxing stretches”?
"Never..." Rin murmured with her eyes closed, "I will never underestimate you again."
"I hope so," she laughed, kissing him on the cheek. "We'll do it again tomorrow."
"Don't even think about it..." Rin replied, sinking further into the sofa, completely defeated.
