Dormitory!

Got it! Here's the revised version with those changes:

A week had passed since that day.

Life continued as usual—uneventful on the surface yet quietly shifting beneath.

Renji's days were mostly the same: wake up, train inside his room, study a little, and then sleep. His body had been changing at a rapid pace, but it wasn't until recently that others started noticing.

Especially Rika.

Sitting on the dorm's common room couch, she absentmindedly tapped her fingers against the armrest while glancing at Renji, who had just walked out of the bathroom. His damp hair clung to his forehead, a towel lazily draped around his neck, revealing a physique far more refined than what she remembered.

"…Hey."

Renji raised an eyebrow at her odd tone. "What?"

Rika squinted. "You definitely didn't look like that a week ago."

At her words, another voice chimed in from the side.

"Right? I was thinking the same thing."

Renji turned to see one of the dorm's other tenants—Daiki, a third-year who spent most of his time gaming or skipping lectures. He sat cross-legged on the floor, controller in hand, but his attention was now on Renji instead of the screen.

Daiki pointed at him with a lazy smirk. "Dude, what the hell? You went from average high schooler to some elite athlete overnight. Are you secretly on one of those weird Hollywood transformation programs?"

Renji clicked his tongue. "You guys are exaggerating."

"No, no, we're not," Rika insisted, standing up and walking over. She poked his arm, then immediately recoiled. "Holy crap, that's solid. That's really solid."

Daiki whistled. "Bro, just tell us the secret. Are you eating something new? Special diet? Super soldier serum?"

Renji let out a sigh, running a hand through his hair. "I already told you. I've just been exercising."

Rika frowned. "Yes, but how? You never even leave your room."

"I train inside."

She stared at him for a moment before sighing. "Okay, I know you told me about your—uh, past-life incident and all, so I won't ask dumb questions, but still… this is kind of crazy."

Daiki stretched his arms behind his head. "Well, whatever. As long as you don't start glowing or flying, I won't question it too much."

Rika, however, wasn't as easily convinced. She crossed her arms, her usual bright demeanor dimming slightly as she gave Renji another long, pondering look.

"You really do feel different," she murmured. "It's not just your body—it's like something in you shifted."

Renji didn't respond immediately. He wasn't sure what to say to that.

Sensing the mood getting heavy, Daiki quickly clapped his hands. "Alright, alright! Since Renji's the new dorm's secretly ripped guy,' how about we make him show off? Arm wrestling match?"

Rika blinked before grinning. "Oh, that's a great idea! Let's test how strong you actually got."

Renji groaned. "You guys are annoying."

But as they dragged him toward the table, he couldn't shake the feeling that Rika's thoughtful gaze hadn't left him for even a second.

Rika leaned forward, resting her chin on her hand while watching him with a pondering look. "Hmm... I mean, I don't mind a little glow-up, but this is more than just that. You've been staying in your room all day, barely coming out except for food or the bath, and now you look like some fitness model?" 

"I just started exercising," Renji replied nonchalantly, grabbing a bottle of water from the fridge. 

Rika pouted, puffing out her cheeks. "Liar. No one gets abs in a week from just 'exercising.'" 

Before Renji could reply, another voice joined in—this time, a teasing one. 

"Oh my~ I was wondering why the common room felt warmer. Turns out, it was our little Renji-kun who turned into an eye candy." 

Renji turned to see Naomi leaning against the doorframe, a towel wrapped around her head, her damp, dark-brown hair cascading over her shoulders. She was one of the dorm's tenants, a university student known for her mischievous nature and habit of teasing the younger residents. 

"Renji-kun, you're hiding some secrets, aren't you?" she grinned. "Training in your room, coming out with that kind of body... what, are you preparing for a debut as an idol?" 

Renji sighed, sipping his water. "You guys are overthinking this." 

"Oh? Then how about explaining it properly?" 

Before he could respond, the sound of wooden sandals tapping against the hallway floor interrupted the conversation. 

"Hoho, it seems my dormitory has gotten livelier." 

An elderly woman entered the common room, her presence commanding immediate attention. Despite her age, she carried herself with grace and a sharp gaze. 

Rika immediately straightened up. "Grandma."

Madam Kaede, the owner of the dormitory and Rika's grandmother, observed Renji with a curious glint in her eyes. "Renji-kun, you've certainly changed. A week ago, you were no different from a twig, yet now you resemble a young warrior." 

Renji scratched his cheek awkwardly. "I just... wanted to improve myself." 

Madam Kaede chuckled. "Well, as long as you don't break the dorm rules, I have no complaints." She then turned to Rika and Naomi, giving them a knowing smile. "But it seems you've caught the attention of the girls. Be careful not to cause any trouble, young man." 

Rika flushed. "G-Grandma!"

Naomi simply laughed. "Well, can you blame us? A week ago, he was just Renji. Now he looks like someone out of a Shoujo manga." 

As the conversation continued, two other female tenants entered the common room—Miyu, a quiet yet sharp-eyed university student who often buried herself in books, and Ayane, an energetic part-time model who always carried an air of confidence. 

Miyu adjusted her glasses, giving Renji a once-over before nodding. "It's an impressive transformation." 

Ayane, on the other hand, let out a low whistle. "Damn, if I knew you'd turn out like this, I would've paid more attention to you sooner." 

Renji exhaled. "I'm seriously regretting coming out of my room." 

Rika, still watching him with an unusual expression, finally spoke up. "You said you just wanted to improve yourself... but why so suddenly?" 

Renji met her gaze. Unlike the others, her question wasn't just teasing curiosity—it was genuine concern. 

After a brief pause, he replied. "I just had a wake-up call." 

Rika's expression didn't change, but her eyes lingered on him a little longer than usual. 

"…I see."

She didn't push further, but something about her tone told him that she wasn't done thinking about it.

As Renji sat in the common room, surrounded by the dorm's female tenants, he couldn't help but feel like an animal under observation. Each of them had their own reactions to his sudden transformation, but beyond the teasing, there was something else—curiosity, intrigue, and perhaps even suspicion.

He glanced around at the women who shared this dormitory with him. Though they were all vastly different in personality, they had one thing in common: they were all undeniably beautiful.

Rika Fuyuzuki: The Childhood Friend with a Cheerful Mask

Rika was someone Renji had known for as long as he could remember. She was practically family, but not by blood—her grandmother owned this dormitory, and since Renji had lived here for years, they naturally grew up together.

Naomi Shirasaka: The Playful University Tease

Leaning against the doorframe with a smirk was Naomi, the mischievous university student who had lived here for the past two years.

Her long, dark-brown hair was currently damp from her bath, her towel loosely wrapped around her head. With a slender yet curvy figure, she always carried an air of relaxed confidence, as if nothing in the world could truly bother her. Naomi had a habit of teasing anyone younger than her, and Renji had been her favorite target for a while now.

Miyu Hoshino: The Quiet and Observant Bookworm

Sitting on the couch with a thick book in her hands was Miyu, the calm and mysterious university student who preferred solitude over socializing.

With long, straight black hair and piercing violet eyes hidden behind thin-framed glasses, Miyu had an elegance that felt almost untouchable. She rarely spoke unless necessary, but when she did, her words were always precise.

After giving Renji a glance-over, she simply adjusted her glasses and said, "It's an impressive transformation."

That was it—no further comment, no teasing, just a simple statement. But somehow, it felt like she had already analyzed him from head to toe.

Ayane Tachibana: The Confident Model

In stark contrast to Miyu's quiet nature, Ayane radiated an energetic and outgoing vibe.

With wavy blonde hair and striking blue eyes, she had the natural charm of a model—which made sense, considering she actually was one. Even in casual clothing, she exuded confidence, standing with perfect posture and a playful smirk on her lips.

"Damn, if I knew you'd turn out like this, I would've paid more attention to you sooner."

Ayane was direct, always saying exactly what was on her mind. She was the type to speak before thinking, and her words often left people flustered—though Renji had learned to just ignore her flirtatious remarks.
