Mystery behind the secret door

AWAY FROM SCHOOL

   After a while, Agatha and Alexander decided to go look for their Mom but before that they need to get out of the school,so they need to find a way to inform the headmaster and their dads.
    After a while of thinking about how to inform the headmaster, they finally gathered courage to go to the headmaster, when they got there, Agatha told Alexander that she would do all the talking and Alexander agreed.
       "What brought you guys here by this time of the day"the headmaster asked
    "We wanted to tell you something important"Agatha replied
       "Something like what"the headmaster asked looking at them curiously
   "We.........."Alexander interrupt Agatha
"We wanted to tell that we're leaving the school, I mean we can't find our Mom in the school premises,we need to go out side the school gate were I have been since my life, this is not just for our Mom but also for us,it is the opportunity for us to explore the world, find out what we don't know,be normal teenagers, being here is like being in jail for a crime you didn't commit and I hate it"
            "I told that I would do the talking, didn't I?"Agatha murmured
"Out there is dangerous for supernaturals like you guys and you guys are the perfect, you guys supposed to be preventing others from making this type of mistake not the other way round "
     "Dangerous you say,we saved the world and nobody except our school knows, nobody knows that we exist outside the world and if you can remember, Agatha and I saved the world "Alexander said
     "If you leave, don't come back "the headmaster said
   "Then we would leave, to our mother " Alexander said
    "Yes to find our Mom "Agatha repeated
"I didn't expect this from you guys "the headmaster complained
     "Neither did we expect this from you " Alexander said while trying to leave
  "Am so disappointed "Agatha added and they left
    When they left, they had no place to go and they started thinking twice about leaving the school , after a while they started feeling hungry,due to hunger they fainted.
     After a while, Agatha woke up but can't find Alexander but can't find her and it broke her down,a lady came out of the gate (she was sitting in front of) and Saw her all dirty and skinny, the lady invited Agatha in and Agatha explained everything that happened to her, and that was how the lady and her husband adopted her.
   

                   A    YEAR LATER
Agatha was already comfortable with her new family and it was her birthday and her mom bought cake
     "Mom, is this cake for me?"Agatha asked
"Yes, I mean you are the birthday girl"her mom replied
    "So................."Agatha was interrupted by the sound of the door
    "Am home"Agatha's dad said
"Dad(she said stretching it) what are you hiding"Agatha asked
     "Mmmm, let me guess what I am hiding,mmmm, presents for you"her dad replied
      "But that's a lot"Agatha said
"We are billionaires, so that is not a problem"
    "Thanks dad"Agatha said
"What of me"Agatha's Mom asked
     "You too Mom"Agatha said
The family started celebrating and Agatha fell asleep and her dad took her to her room.
       The next morning, Agatha woke up and went to her parents room to greet them, but they were no where to be found, Agatha started shouting their name but no one responded and that got her scared, she went down stairs and saw her parents in a pool of blood and she shouted as she was going closer and found out that her dad was still breathing
    "Dad,dad wake up, don't leave me all alone"Agatha said while crying
  "Run....... Run......Run for your life, they're coming for you"her dad said
   "But..........but........but I can't leave you here all alone"Agatha replied
     "Go, don't........... worry........ about........ me"Agatha's dad said and that was when Agatha started running
      Luckily for her, she got adopted again by a poor family but only her mom (the lady that adopted her) loved her and not her Dad.
      "Agatha, you would be late to school"Christie said (Agatha's Mom)
     "Ok mom I am coming"Agatha replied
After a while Agatha was done with her food and everything she was doing and left for school and went to her class
     "Here comes the orphan"Angela the bully said immediately she sighted Agatha
    "What a world, Agatha was once richer than us and now poor, what a poor little girl"Billy said
     "And I think her grades are as poor as she is"Angela said again
    "Point of correction,her grades are better than than yours"Ivy(Agatha's friend said)
    "Meaning that your grade is as poor as a church rat"Nora (Agatha's friend) said
   "Shut your traps before I do it myself"Angela shouted
  "Awwn, the queen of the class is angry"Ivy said in a childish tone
    "You irritate me"Billy said
"And you..................."Nora got interrupted by the teacher
      "Everybody on your sit"the teacher instructed and everybody rushed to their sit
      "I want you guys to welcome your new classmates (turns to the new students) come and introduce yourself"the teacher instructed

     "Are you guys twins"Agatha asked
"Who gave the orphan the permission to talk"Angela said
      "Yes we're"Charles replied
"Instead of bullying people,why not focus on your grades"the teacher told Angela and everybody started laughing at Angela and the teacher left
   "I hate this teacher "Angela murmured
"OMG "Billy shouted
     "What Billy "Angela asked
"The two new students are the children of the famous Grandes "Billy said
    "Are you serious? "Angela questioned
"Am very sure"Billy replied

    "But we want to sit here and not there, so mind your business, right Charlotte?"Charles asked
    "Yes Charles"Charlotte replied
"Nerds"Angela said and left the class and Billy followed

"Ummm, what's your name?"Charles asked
      "Am Agatha"she replied
"And I am Charles"Charles said
    "I know"Agatha replied
"How?"Charles replied
   "You introduced yourself few minutes ago"Agatha replied
     "Why do you allow those people bully you "Charles asked
     "I don't have a choice and am broken " Agatha replied
     "What happened?"Charles asked
"Don't ask her about her past,or else "Ivy said
   "Or else what?"Charlotte asked
"You would see the other side of her,and trust me you would regret it "Nora said
