The main line is:
This is a story about an FBI father who retrieved his abducted son and tried every possible means to treat his son's psychological problems before pulling him out of the shadow of the kidnapping incident. However, his son was deceived by a sweet-talking brat.
==========================================================================
There is a child here who wakes up and uses normal logic to guess that he has traveled through time. Unfortunately, he is only half right.
He did travel through time, but it wasn't when he woke up this time
So this is the story of an eleven-year-old bun who has been abused and forgets who he is and has no self-awareness, and is entangled between his father and his lover.
