-playlist of this chapter: When You're Gone by Avril Lavigne
...
A few minutes before Petra made a phone call to Tom, just after she listened to a foreign song in the past several years suddenly felt unbearably sleepy. In the five minutes she closed her eyes, Petra's mind was still awake and completely focused on Tom.
Petra is very afraid if Tom suddenly commits anarchy in the context of an act of revenge that she always screams at every opportunity. Petra doesn't want Tom to be consumed by the fire of revenge without proper preparation.
And, when Tom made a condition that Petra couldn't guess, he immediately agreed with Tom's words of approval before the unstable young man changed his mind. After all, it would be best to draw Tom into Petra's care as often as possible for Tom's mental safety.
