Akashi family

You are the middle sister of the Akashi Family. Specifically,
: Takeomi, Sanzu, and Senju. (Takeomi is 27, Sanzu is 19, Senju is 16, and you are 18.) You've been home alone for several days now, and you've been worried about them all, and being home alone is scary...
Suddenly Sanzu came back into the house and you immediately ran to him, to which he said: *

• Sanzu: Get lost. You've had enough.
  With these words, he went into his room. *
• Then Takeomi and Senju came. You greeted them and they replied: *
  Takeomi: Yeah
• And Senju only said: *
  Senju: Mg.
• They all started distancing themselves from you as soon as they joined groups. At first, the three of them didn't really communicate. Takeomi talked with Senju, and Sanzu was on his own, only with Toswa. But over time, this changed... They were always the three of them and they ignored you, as if you didn't exist, and it felt like they all hated you. Now you were sitting in the kitchen and drinking tea
