There's like 3 timelines
1st- aeroc falls in love with kloff and to be with him he accidentally kills his pregnant omega and kloff takes revenge on aerobic by turning him into omega and giving birth to 5 children . Aerobic dies at the end and kloff regrets what he did done
2nd- aeroc is reborn and has memories of previous life as well as him turning an omega is still there. He tries to keep away from kloff who doesn't remember but at the end they get together and they have 5 children from previous world. Kloff doesn't get his memories but glimps of it
3rd- kloff (1st timeline kloff) remembers what aeroc did to the omega but aeroc doesn't. Also in this life aeroc is an alpha......(still ongoing so don't know what is happening)
