So things develope and apparently only Matthew knows they are destined mates. He goes to rut in jealousy and is pretty controlling and rough and marks and knots without concent.
After that the black haired omega (Hayoung) went back to Korea with his parent .Matthew has gobe to look for him. He succeeded in convincing him and asked him to marry him
Season two is... uh... dark.
