Haikyuu!!
So this is an A/B/O universe where it centers around the Miya twins, Suna, and Sakusa.
So the Miya twins are omega street rats while Suna and Sakusa are rich bitches who are alphas.
The Miya twins are hiding huddled together inside a fucking tiny ass cardboard box to shelter themselves from the rain when Suna and Sakusa see them and take them in. They don't live together, but they keep the twins at Suna's place where they're taken care of and well fed.
Other rich men find out about the Miya twins and twins omegas are rare so of course everyone wants them.
Suna and Sakusa are offered lots of money but they refuse.
Eventually Suna falls in love with Osamu and Sakusa falls in love with Atsumu and vice versa.
Of course, things are still complicated and there are lots of problems.
Eventually the Miya twins try to convince Suna and Sakusa to let them go because they're worried that they're being burdens which 😭😭
Things are worked out and resolved, and bam.
Everything's back to normal.
Except they all become mates and they all live together and live happy lives.
The end.
Not much idea with that lol.
