With my badass ambidexterity, I blasted through the punishment worksheets at nearly double speed, then carried Yeeun home on my back as a thank-you.

Yeeun’s mom seemed worried since her kid was out late, but when she saw me piggybacking her, she just smiled faintly and didn’t ask what happened.

By the way, the teacher who assigned the worksheets had already gone home, so I couldn’t submit them directly and just left them in the designated drawer in the staff room.

Naturally, I didn’t get back my gym clothes, which the teacher had confiscated as evidence.

It was hard to explain, so I just told my mom I probably lost them.

But more important than these little things was something else.

As soon as Mom served dinner, I greeted her and picked up my chopsticks with my right hand.

I’m pretty good with chopsticks in my left hand, so I’d never used my right, but as expected, it was a bit clumsy at first, then quickly became smooth.

Like I’d been doing it for 20 years.

For the final test, I even picked up individual grains of rice—down to single grains.

Seeing it work for real got me even more hyped.

I scarfed down dinner, grabbed a random ball, and headed to the playground in front of the house.

It wasn’t a proper soccer ball, just a bouncy one for dodgeball, but whatever.

In this life, I’d focused on baseball, so I hadn’t played much soccer and was awkward at it.

I started dribbling around the playground’s perimeter, tapping the ball lightly.

First, with my dominant left foot, of course.

I’d never properly learned soccer, so I sucked, but I could manage a light jog while dribbling.

Next, I switched to my right foot.

At first, it was so awkward I couldn’t control the power—kicking it too far or too close, tripping myself, no speed at all.

But as I kept dribbling at walking pace, that familiar sensation kicked in.

Eventually, I could dribble at a gentle run.

Then, alternating feet for a two-footed dribble while running.

Tapping with each step made it way easier.

By the end, I could dribble at nearly full sprint.

Even more excited, I went home and tested more stuff.

I juggled with an air-filled toy ball, alternating left and right hands.

Drew pictures with both hands.

Grabbed scrap fabric and sewed with both.

Even hopped on one foot, switching sides.

All tests perfect.

For the final crucial check, I told Mom my eyes felt weird and suggested seeing an eye doctor.

Mom freaked and wanted to skip school tomorrow for it, but I convinced her to go to a big university hospital instead.

“So, in all my years as a doctor, I’ve never seen a case like this…”

The doctor started awkwardly, and Mom tensed up, squeezing my hand.

“Doctor, is something wrong with my child? Is it a serious health issue?”

“No, ma’am. It’s my first time seeing this, so I can’t say for sure, but I don’t think it’s a health problem.”

“Huh? What do you mean?”

“Ma’am, have you heard of a dominant eye?”

“Dominant eye?”

The doctor spun his chair, grabbed a head model, and pointed as he explained.

“Like hands, eyes have a dominant one you use more and a non-dominant one. That’s the dominant eye.

People feel discomfort looking sideways in the direction opposite their dominant eye.”

He demonstrated by shifting positions around the face model, then pointed at me.

“The dominant eye is fixed for life. You said your eyes felt off, so there must be something unusual, but basic tests showed nothing wrong.

After various tests, including dominant eye checks, I figured it out.”

He showed my test results.

“This is a unique case… Your dominant eye is basically the left. It’s not always the case, but dominant hand and eye often match, so that’s not unusual.

The issue is that at certain viewing angles favoring the right, it suddenly switches to the right eye.”

“Huh? So is that a problem?”

“I’m sorry to speculate without precedents, but as I said, I don’t think it’s a big issue. This hasn’t been reported in academia, so I’m stumped too.”

Still, to rule out unknowns, he suggested more tests, including brain scans.

He offered to waive extra fees if we allowed a paper on my case—good, no worries about costs.

Honestly, what I heard at the hospital was what I expected.

From personal tests and sensations, I’d guessed my ability.

In this life, as Kim Yiseon, I’m left-handed, left-footed, left-eyed dominant.

But in my past life as a manga fan, I was right-handed, right-footed, right-eyed.

When you reincarnate, how far do memories go? Just text or video knowledge?

What about felt sensations or stimuli? Aren’t they memories too?

I still remember tastes from past-life foods—that’s sensory memory.

If sensations are memories, then body movements are too.

So, reincarnating, I can recall right-hand sensations from my past life on this left-dominant body.

Plenty of people are ambidextrous or two-footed, but they’re just good with the non-dominant side.

My case is different: current left and past right—truly both dominant.

Even the unchangeable dominant eye switches to right like my past life, somehow.

I’m the world’s only fully symmetrical human.

It’s a reincarnation perk that hits every guy’s dream.

We all envied ambidexterity as kids.

Cool heroes wield dual swords or dual pistols, right? Or switch stances for combos—didn’t that make your heart race?

Whether Yashin intended it or not, he knows how to tug at guy hearts, even if his stories suck.

This perk oozes coolness.

Right after the hospital, I skipped workouts and went to Yeeun to thank her for helping discover this badass trait—and brag.

“So? I get you can use both hands well. But what’s it good for?”

Yeeun stared blankly, not getting this massive ability. Guess girls can’t grasp a guy’s romance.

“You wouldn’t know, but with both hands skilled, I can dual-wield swords.”

“What, you gonna swing knives around?”

“And dual pistols too.”

“Can’t shoot guns in this country.”

“I can take notes left-handed while surfing the web right-handed.”

“That’s super mundane.”

At first, she pondered if it was really amazing since I thanked her, but now her look was back to normal pity for me. But this is seriously huge…

“Girls just don’t get it. Guys would all say it’s badass.”

“Yeah, yeah, got it, now go home. Your mom’s probably looking for you.”

“It’s no joke. I can dribble with both feet too.”

Yeeun turned me around like I was some deficient kid.

Well, I thanked her, so mission accomplished.

You’ve probably guessed, but the most badass part of this perk I haven’t mentioned yet.

“If I can dribble with both feet, what’s stopping me from throwing with both hands?”

Yeah.

If the arm and shoulder blow out from overuse, just split it between both arms, right?

The torso and legs are used the same either way, and the injury was shoulder and elbow, not waist or hamstrings.

Switch-pitchers are rare but exist.

Research is lacking on body strain, though.

But with a confirmed glass body, who cares? Gotta use what I got.

I started revising my future plans, pondering how to max this badass perk.
