Swimming System: My Childhood Sweetheart Wants to Win Even More Than the Coach

Eighteen-year-old Zhou Yun has a Korean childhood friend who's ridiculously beautiful and ridiculously confident.

Kang Ina is a trainee attracting attention before her debut.

She believes she's destined to become a top-tier star, and she's just as sure that Zhou Yun will one day surpass swimming prodigy Jiang He.

From then on, she throws herself into dance practice while he adds extra training.

She prepares to take the stage, while he sets his sights on the podium.

It isn't until the cameras pan across the stands at the world championships that people notice the popular Korean star cheering louder than the coach.

Everyone praises her for having a good eye and picking a future champion early.

Only Zhou Yun knows...

When she first came to cheer him on, he hadn't even made it to the finals.
