Shi Miao, younger sister to Shi Fen, grows up in a fractured household—abandoned by her mother in childhood and navigating her father’s alcoholism. With Shi Fen reluctantly stepping into a caretaker role, their bond thrives on chaotic banter and physical scuffles spurred by his pranks, yet shifts seamlessly into fierce loyalty when facing external threats.

A disciplined student fixated on academic achievement, she wrestles with balancing ambitions and personal interests. A childhood dream of dance classes derailed by her father’s error lands her in martial arts, honing combat skills that fuel both her short fuse—often unleashed on Shi Fen—and a pragmatic resilience that anchors the family.

Protective yet guarded, she shields loved ones fiercely, bonding with Miaomiao, a cheerful classmate whose levity offsets her intensity. Romantic entanglements complicate her world: unspoken feelings linger for Zhen Kaixin, Shi Fen’s best friend, while Wan Sui, a secretive transfer student from wealth, pursues her. Sibling rivalry amplifies these tensions, as seen in clashes over parental vouchers—her insistence on earnest connection battles Shi Fen’s trickery.

Over time, she begins recognizing Shi Fen’s quiet generosity beneath his carefree facade. Though conflict resolution remains blunt, shared meals and teamwork hint at deeper empathy. Academic stress and romantic missteps chart her growth, revealing a young woman learning to weave ambition with the fragile threads of family and friendship.
