Once the sexual novelty wares off, they will either break up and go back to their respectable races……
OR
They will have kids asap and ignore the shortcomings in their actual relationship by putting all of their attention on their children… they will push their daughter towards academics and push their son towards athletics…
All of their extra money will go towards luxuries and exotic vacations to portray the falsehood that they live the perfect life…. Filled with materialism and aesthetics.
THE END
