Episode 1: The “Bikí!” That Started It All

It was a weekday morning. Since turning fifty, I’d become conscious of my declining stamina and made it a point to run at least a few times a week. Of course, “for my health” was just the excuse; deep down, it was rooted in a strangely youthful pride—a desire to remain someone who could still run.

My family was still asleep. In the quiet morning air, I laced up my running shoes. The temperature was low, the sky a faint blue. This kind of air has a dangerous charm that somehow makes you think, “I can do it today.”

I started running slowly, passing through residential areas and circling a few parks. I felt fine. Light, even.

“I could probably run a bit extra today.”

That was the problem – that casual thought popped into my head. When people feel good, they tend to overestimate themselves. Probably half the failures in the world happen because of this “I feel like I can do it” feeling.

And then, just after passing the turnaround point, as I reached the area farthest from home.

——CRACK!!

A sharp pain shot through the outside of my left knee.

“…!”

A soundless cry escaped me. The shock was so intense my legs stopped, and I could only stand frozen in place.

The pain felt like an electric shock.

Not figuratively—I genuinely thought, “Did I touch a live wire?” It even felt like my heart had stopped for an instant.

I frantically scanned my surroundings, trying to cover it up with nonsensical actions, but a commuting salaryman spoke to me.

“Are you okay?”

“Um… my knee… it just… snapped…”

“Snap…?”

“Ah, sorry, that was a clumsy way to describe it.”

“No, it’s… take care…”

I was completely treated like a weirdo. I was serious, but it didn’t register with him. This was the “misunderstood laughter.” Life sometimes throws in this kind of cruel humor.

When I tried to walk, the pain shot in a different direction.

With every step forward, regret washed over me like a wave: “Why now?” Of all places, it had to break down at the farthest point. It was enough to make me want to collect statistics on life’s terrible timing.

After walking a bit, I passed a group of elementary school kids walking to school.

One boy saw my awkward gait and whispered to his friend:

“Look, that guy looks like a zombie from a movie.”

“No, it’s not like that… He’s actually really serious…”

But my words drifted away on the wind, never reaching the children.

“Practicing to be a zombie? For the school festival?”

No, I’ve never practiced being a zombie in my life. I don’t recall ever taking on that kind of role.

Finally reaching home, I struggled to take off my shoes at the entrance when my wife, Misaki, woke up.

“What’s wrong? You look like you’re dead tired…”

“My knee… it suddenly started hurting when I turned back…”

“Turning back… I wish it had hurt closer to home.”

“If I could do that, I wouldn’t be in this mess…”

My wife laughed a little and showed concern, but our conversation was slightly out of sync. This too was a smile born of a misunderstanding. The person involved is serious; those around them have a slightly skewed understanding. That’s just how family life is.

Even past noon, the pain wouldn’t subside. Sitting at my computer working, I typed in one forbidden search term after another.

“Knee excruciating pain outer side” “Running can’t walk” “50s knee done for”

The search results were basically all despair-inducing. The more I read, the darker my mood grew. The darkness of online medical information runs deep.

A chat came in from my coworker, Kitagawa.

“Hey, boss! You were running this morning! That’s awesome!”

“Nah, my knee… might be broken.”

“Huh? That’s a metaphor, right?”

“Physically, maybe…”

“Haha, you’re in a great mood today!”

I was dead serious, but he treated it like a complete joke.

I thought to myself.

“In life, the things that matter most are the hardest to convey.”

While continuing work, tossed by waves of gloom and pain, a single word jumped out at me from my phone’s ad section.

“Improve Knee Pain with Regenerative Medicine – What is PRP Treatment?”

PRP?

What’s that?

My first thought was “A new kind of yogurt?” – a completely off-base image. Human imagination is surprisingly useless.

Yet this was the first “touchpoint” that would change the course of my life.

Little did I know then that it would lead to something far greater than I could have imagined.
