Can someone refresh my memory? Who is Kais and Herhal (I forgot his name)?

Sounds like the ML kais and maybe herhal was the brother? I don't remember either lol

Kais is the ML, Harrel is Kais's younger brother who was saved by Amel

Kais was the original ML, and Herhal is his brother who was originally supposed to be killed by Kais because he would rescue him to late and Herhal became a monster. but because the MC intervened with the plot she ended up meeting the ML early and also saving Herhal by using resurrection magic. that’s also why Herhals hair turned white. (it was originally black). also that’s why Herhal calls the MC Angel.
