Would he fight her for her daughter?Gu Qingchen could never have imagined that the chubby little bun in front of him was actually his biological daughter!“Bei Ran, you hid it from me for five years, always flawlessly obedient before me, tell me, how should I punish you?” Gu Qingchen raised a bloodthirsty smile.Could she possibly not tell him there is also a son who looks just like him!Theater Version:The teacher informed Bei Ran that her son had used a scalpel in school to investigate the cause of death of poisoned small animals.
