Reborn Through Transmigration

The main plot is:

This is the story of an FBI father who finds his kidnapped son, then pours his heart and soul into carefully and patiently doing everything he can to treat the boy's psychological problems. Just as he finally pulls his son out of the shadow of the kidnapping, the boy gets lured away by some smooth-talking brat.

There's a kid who wakes up and, reasoning logically, figures out that he must have transmigrated. Unfortunately, he's only half right.

He did transmigrate, just not when he woke up this time.

So this is the story of an eleven-year-old dumpling who, after enduring severe abuse, has forgotten who he is and doesn't even realize it, caught between his dad and his lover.
