Rezef is half-sibling to cayane(considering they share the same mother).cayane is from the emperor and empress while rezef of empress and raphael's dad.
Here,they are not related by blood at all considering the fact that ran was is not of lachia's blood.
Remember half-siblings and step-siblings are different.

ML is the step bro and they ended up together. NO THIS IS NOT INCEST BECAUSE THEY ARE NOT REAL SIBLINGS. NOT BLOOD RELATED AT ALL. MC IS ONLY RELATED TO ML ON PAPER BECAUSE HER MOM MARRIED HIS DAD.
He realizes his feelings for her when she was tryna save the 2nd ML and when home drenched in the rain and injured. Ml was mad and walks outbut then realizes he loves her (▰˘◡˘▰)
Time skip. Ml finally is an adult and can inherited the title. Confesses to mc but mc reject. He basically has to pursue her which i think is also cute.
in the end they had 2 kids. girl and a boy.
