Erased/Boku Dake ga Inai Machi de

Well...I’m still on book 3 which is the book where Satoru loses his memories and meets Airi, then the book ends so I need to get book 4...but WOW!!! Book 3 was INTENSE! I cried at the end!!! And so did my weeb friend...I don’t get that part in the Teacher flashback where he quotes “And then I realized my brother hadn’t asked me “What had I done” meaning “Why hadn’t you stood put and watched out for me”...” ???? WHAT??! And the they show a bag of sunflower seed which was used to feed the hamster...??? MY FAVORITE character is the MOM!!! 10/10 BEST CHARACTER!!! She’s AWESOME!!! A TRUE HERO!!! Omg!!! And I was so heartbroken when they Showed Kayo and her child...I felt SO betrayed...and then I was happy cuz I shipped Kenya x Satoru!!! This series is the reason why I have no faith in teachers!!!
