And I guess a lot of viewers were wondering the same thing as you, so the author did another what if scenario where aeroc does not die and instead lives in the first timeline (survives the twin birth). I think this is the last last volume.
This is not canon. The original aeroc and kloff do not meet (and I’m very glad because kloff does not deserve aeroc) this is just showing the viewers what would have happened if aeroc lived.

uh ok so both of them regressed in the same lifetime right?? like the ml and mc in the current chapters were the ones from the starts??
