Three years later, Dai Qingshu secretly returned to the country.

His plan was simple: cripple Gu Qingyu and take his place.

If Gu Ting had only one outstanding son left, then he would have to take Dai Qingshu seriously.

By that time, he would definitely be reluctant to use a fake paternity test to deceive his real son.

So what if he was an illegitimate child? In the world of the wealthy, it was commonplace.

Gu Qingyu's schedule and security were very tight, making it difficult for Dai Qingshu to get close.

The appearance of Ling Ai was an unexpected variable.

Dai Qingshu meticulously planned and approached her step by step.

Under Ling Ai's cold exterior, her heart still harbored fiery longing, which Dai Qingshu keenly picked up on.

Ling Ai began to feel dissatisfied

with her contractual marriage, scrutinizing her choices, and wanting to try changing things.

But it was too late, and the Gu family did not agree. Ling Ai felt miserable and fell into depression.

The depressive emotions accumulated bit by bit, and with the wedding fast approaching, Ling Ai reached her breaking point and called it off with Gu Qingyu.

Enraged and humiliated, Gu Qingyu had an argument with her, and in a fit of rage, accidentally killed Ling Ai.

At this point, Dai Qingshu broke down in tears, confessing to me: "Ling Su, I'm sorry, I let your sister down. I never thought it would end like this. I was wrong, I was really wrong."

Heh, a light "I'm sorry" worth as much as three lives?
