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

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.
I finished chapter 42, I feel like the story is a bit dull. Is it worth finishing it?
Depends on why you find it dull. If the Ehirite fragments and Keira plot point/FLs backstory is why you aren’t enjoying it then I don’t think it’s worth finishing since they become more relevant as you go on. However, if it’s because the ML and FLs relationship hasn’t developed much/it feels very one-sided on his part then I think it’s worth finishing. I will say that the middle can be very frustrating with some misunderstandings/lack of communication but I enjoyed most everything after that. However, it’a totally fine to not like this story. Maybe it’s just not for you.
