I Was Reincarnated as a Creepy Fat Guy, Then Trained Myself Without Sleep. And Then, for Some Reason, the Heroines Start Approaching Me - Chapter 4: Summer Vacation Accomplishments

Our movement, led by us for us, began. On relatively cool mornings, we did aerobic exercises outside, worked out at home during hot afternoons, and held reflection sessions in the evenings. The routine I devised may have seemed harsh at first glance, but there was no other way to achieve results quickly. Fortunately, Manabu and Keisuke, despite occasionally expressing doubts, stuck with me without giving up.

Moving a massive body that exceeded 120 kilograms required blood, sweat, and effort, but my motivation grew with each passing day as I confirmed the decreasing weight.

Above all, it was enjoyable because I wasn’t alone; I was accompanied by my precious friends. Occasionally, thanks to my parents leaving the house, the three of us talked about things we hadn’t discussed before, encouraged each other, and our bond deepened gradually.

And before we knew it, summer vacation was coming to an end.

After following our usual routine, we stood in front of the bathroom scale. It was 5:50 PM, just before dinner.

“Itsuki…”

“Yeah, I know.”

Nervously, I bit my lip, and Manabu, not with his slender body but with an impressive, trained physique, placed his hand on my shoulder. He wore contact lenses instead of round glasses.

And Keisuke, with his striking long hair, looked at me with clear eyes and nodded.

Seeing their reactions, I took a short breath and stepped onto the scale.

“77 kilograms.”

The moment I saw this number, my heart raced, and my lips curled up naturally.

“I did it! I did it!”

Then, I looked at my reflection in the mirror next to the scale.

With slightly longer black hair, well-defined features, and a broad, well-toned body in an impressive inverted triangle shape. Muscles that looked strong were visible in my arms and chest, and there was a six-pack on my stomach. My skin was fair, and though it might sound immodest, I could be considered quite handsome.

I was so overjoyed that I hugged the two of them with my well-trained body. Then, Manabu, who used to be a bookworm, spoke up.

“Yeah, just a month ago, you were called a fat nerd in class, but now you’ve turned into a handsome guy.”

“You too.”

“…Itsuki-kun, your parents have good-looking faces, so it might be genetic…”

“Keisuke, you’ve become much more talkative compared to before.”

“R-really?”

“Yeah.”

“…I’m happy.”

With long hair, Keisuke smiled and looked at me. Then, Manabu, who was beside me, suddenly gave me a puzzled look and asked.

“By the way, Itsuki, I’ve been curious about something. Did you do sports in the past?”

“N-no, this is my first time.”

“Hmm… considering your knowledge of exercise techniques and diet, you seemed unusually well-informed…”

“That… well, I just watched tutorials on YouTube and copied them…”

I couldn’t possibly admit that I used to be a gym trainer in my previous life.

As I casually moved away from the two and avoided eye contact, the socially awkward Keisuke spoke up.

“Um…”

“?”

“About our summer homework…”

“”Wha…!!!””

Oh, right. I completely forgot about it because I was so focused on working out and dieting.

There was only one week left until the end of summer vacation. Thinking about it, cold sweat naturally flowed from my forehead. At the same time, someone rang the doorbell

“?” 

I made a dumbfounded expression upon hearing the doorbell. Then,

“Oh, it seems they’re here.”

“Who?”

“Itsuki… didn’t we talk about eating outside today? Did you forget?”

“With Itsuki-kun, Manabu-kun, and my family, delicious food…”

“Oh, that’s right.”

Today is the day to announce the results of our workouts. So, our parents did us a favor by preparing to celebrate our daily improvements.

With a warm feeling in my heart, I spoke to the two of them.

“Let’s change our clothes.”

“Yeah.”

After changing and opening the front door, as expected, our parents had smug expressions and gave us a thumbs-up. Then, my mother, with glossy lips, spoke.

“Today, we’re having a party at a quite expensive yakiniku restaurant! For the three of you!”

Saying that, the three of us looked at each other with relaxed cheeks and nodded confidently. Then, something caught my attention: a blue-haired beauty who was hiding behind Keisuke’s parents and sneakily glancing at me. Judging by her hair color, she’s probably Keisuke’s little sister.

I knew that Keisuke had a sister, but she’s quite cute. However, her shyness is just like her older brother’s.

X X X

A yakiniku party with ten people: me, Manabu, Keisuke, Keisuke’s sister, and our parents. Manabu and Keisuke’s parents kept thanking me for changing their sons so much, bowing their heads. It seems that Manabu, with his small stature, had been bullied in middle school, and his parents had been worried for a long time. Keisuke’s parents had consulted with a mental health counselor and even given him medication to reduce his anxiety.

However, during this camp, Manabu had gained some muscles despite his slightly smaller stature. Furthermore, he was no longer wearing his usual round glasses but had switched to contact lenses, making him look handsome. Probably, if he just tidied up his hair, which he had let grow for a month, he would look pretty good.

In Keisuke’s case, he had become quite talkative. Of course, his social anxiety wasn’t completely gone, but he had learned to express his opinions a bit more when dealing with people he trusted.

So, the parents of both boys held my hand throughout the yakiniku meal, tears in their eyes, and expressed their gratitude.

Keisuke’s sister remained mostly silent, focusing on her meal, but occasionally sent glances my way. So, whenever our eyes met, I smiled at her, and she suddenly averted her gaze and returned to eating.

In this heartwarming atmosphere, we laughed and enjoyed ourselves.

School will start soon.

Thinking about the fun we’d have in school with the three of us, for some reason, my heart was pounding.

It was time to say goodbye to Kanzaki, Hayama, and other classmates who looked down on me.　

I would walk through life with these guys.

But before that, considering the mountain of homework awaiting me, I couldn’t help but smile wryly.
