am your brother not your toy (takemichixmikeyxhina)

omega!Mikey
alpha!takemichi
alpha!Hina

Hina is a girl but she very strong than Mikey she can be top Mikey because Mikey is weak in this au .

Guy in this au I don't do Mikey in heat because Mikey heat only come when he was a little kid because he is a special omega and special abilities that he only in heat when he a kid but when he 12 he don't in heat anymore .

Hina and takemichi are siblings so

Takemichi tachibana(boy)
Hinata tachibana(girl)

Mikey is just a normal guy that one day his family die and got adopted by tachibana family that is the rich and dangerous family in the world .they really love Mikey and Hina , takemichi really obsessed with Mikey until one day takemichi and Hina mom and dad die in the car crash and they really hate there mom and there dad because they alway y'all at them and alway take away there time to play with Mikey and before they adopted Mikey they abuse them but when they adopted Mikey they stop for a while but when Mikey go to school they alway hit them when they heard they dead they really happy but not Mikey Mikey is sad because they dead .

They tell Mikey to forget about them but Mikey cant they thought Mikey is just a kid so he can't take it when they family on die Mikey alway talk about them first they don't care but when Mikey get 18 Mikey still talk about them and they start to get annoyed and tell at Mikey and told him to not talk about them anymore and talk about everything's else .

Mikey stop to talk about there parents and start to ignore them and he always come back home late and alway drink and alway flirt with everyone he see . It start to annoyed them and they lock Mikey in the room don't late Mikey come out again .

So what will happen to Mikey

Will they treat Mikey good or bad

Will they do anything to get his attention .
