This is a story about a poor but gentle, honest ballet boy and a passionate, determined boxing boy. The two met at the Children's Center, and since then, they've grown up supporting each other—even in the face of hardships and challenges—as they resolutely pursue their dreams.
The beauty of salad days lies in the sweat from struggles and the nurturing of friendships. Even though the two have completely different lives, what remains the same is their warm feelings for each other...

Because of years of ballet practice, Jiang Shen's foot arches are much higher than those of a normal person. Even though they're naturally flat, the insteps of his feet can clearly be seen as bent.
"Does it hurt?" Bai Jinyi asked suddenly, holding onto his foot.
"It doesn't hurt once you've gotten used to it." Jiang Shen shook his head, rather disdainful of his feet. "They're just really ugly."
"My hands don't look good either." Bai Jinyi showed him the back of his hands. "Look. It's full of scars—the kind you can't get rid of . So, it's okay to be ugly, Little Swan. Let's be ugly together." Bai Jinyi looked at him and smiled.
