The same incident, when confessed by the perpetrator themselves, creates one effect;
while the effect is different when the victim brings forth the accusation.
People show great tolerance when the perpetrator can "repent in time."
For instance, the incident where Seo Xiulan deliberately switched the children and then colluded with He Tiantian to assume a false identity—if it was Zhou Zixuan, the victim, who made the accusation.
Zhou Chuanguo and Feng Mingjie would be shocked, and their anger towards Seo Xiulan and He Tiantian, their heartache and guilt towards their biological daughter, et cetera, would all reach a climax.
And when people are in extreme anger, it's difficult to remain rational, and they might do something drastic.
Now, He Tiantian, as one of the culprits, got ahead of Zhou Zixuan and voluntarily confessed everything.
In meticulous detail, objectively and truthfully, without a single word of defense for herself or Seo Xiulan.
