Lin Yun, 36 years old, lost his wife early on. A mid-level manager in a private company and a single father, he’s been feeling the weight of a midlife crisis lately.

His career has hit a rough patch, his relationship with his 14-year-old daughter is locked in a cold war, and he suffers from chronic shoulder pain that makes every day miserable.

And just recently, he discovered a shocking secret—his daughter is a magical girl.

A young girl, standing against extraordinary monsters, a hero protecting the city from attacks. That’s how the public sees magical girls.

But he knows the truth—being a magical girl is dangerous.

Should he stop her? Or should he respect her choice and find another way to protect her?

Staring at the long-forgotten Heart Blossom gathering dust in his wardrobe, Lin Yun—the former magical girl who retired 19 years ago—faces the third major crossroads of his life.
