I Was the Heroine of a Sports Anime, but Switched Careers to Become an Idol

Hello, everyone. As the kind of girl who transmigrates into a well-known sports anime, I was reborn as its female lead, a character with a name and a face.

As everyone knows, there is no romance in competitive sports.

My role as the female lead was limited to being a major character's younger sister and the manager of the protagonist's club, dedicated to helping my brother get back on his feet.

But...

When my brother really went abroad to study swimming, I looked at the budget deficit in our single-parent household and fell into deep thought.

Could it be that I was actually the only one who could support the family?

So...

After debuting in sixth grade, I became a child star, while my brother trained overseas in seclusion.

By my second year of middle school, I had made the leap to the big screen and become the youngest major-award Best Actress in the country, while my brother was still training overseas in seclusion.

I took a short break from acting in high school to focus on my studies. My endorsement posters came down as their contracts expired, and my brother happened to return home.

To let my brother focus on training, I decided to keep hiding everything from him.

After Rin Matsuoka returned to Japan, he grew prickly and withdrawn, and never reached out first, not even to the younger sister he had once been closest to.

But although he didn't reply to his sister's messages, her presence was still everywhere around him.

A bratty elementary-school kid wearing glasses big enough to cover half his face blocked his way and sternly told him to let his sister know she shouldn't be curious about him.

Rin Matsuoka: "...You're still just a kid, aren't you?"

The handsome captain of the indoor volleyball team next door gazed at him brightly and asked him to pass a gift to his sister, accidentally calling him "Big Brother" along the way.

Rin Matsuoka: "? You're older than me, damn it!"

Some perverted college guy with flames on his head shouted, "Go in with the resolve to die!" as he ran toward him naked, begging him for a signed photo of his sister.

Rin Matsuoka: "Then go die!"

As he rushed to get to a competition on time, a helicopter suddenly swooped down in front of him. A boy with a beauty mark at the corner of his eye reached out and said that anything concerning his sister concerned him too.

Rin Matsuoka: "I'm done competing, screw this!"

There were so many incidents that Rin Matsuoka finally realized something was off. He searched online for his sister and found that, in an old interview, she had said she debuted because "I was so lonely when my brother went abroad to study." Feeling guilty, he finally took out his phone during a break from training and messaged her first.

Rin Matsuoka: What are you doing?

Matsuoka Go: On a date, big bro. I'll talk to you later, mwah!

Rin Matsuoka: ...?
