Their children will not be reborn. The first child in 2nd life is male alpha with black hair like kloff. Aeroc was adamant that his first born will be omega blonde hair, and he was about to name him Rapiel (like his first born on 1st life), Kloff was confused why naming a child to another omega. But when the child born, and he doesn't look like his first born in previous life, aeroc went into frenzy all over again. That part is actually sad, because Aeroc in the end, even in this life, will never be able to meet his children again.
Third life, I don't remember if there's any children. That's all from novel. Idk if manhwa will change it

Does anyone know whether their children will remember the first life too? In either the second or third timeline?
