Payback in Her Shadow

Mingli was dragged by classmates to the school's back hill as a moving target. They chased her with arrows, accidentally hitting her chest. Fearing their bullying would be exposed, they buried Mingli in the mountains - unaware her twin sister Mingyu was already searching for her. Upon learning the truth, Mingyu was consumed by grief and rage, vowing to make the perpetrators pay dearly for harming her sister.
