Just finished it! So they did become a couple in the book, and the series just made their story longer =D I still wished they didn't make Thai similar to the indecisive Sorn lol
1) First there is no way the killer just got lost at an amusement park and her mother didn't find her and waited…
She killed herself because her revenge was already done, and she don't want to go to jail for the murders that she did. She also killed herself by burning herself, the same way her mom died. I see this as her asking for her mom's forgiveness because she accused her of abandoning her when in reality she didn't
