My thoughts are the soul of the brother is the elf who stole R/Lari’s soul, but somehow he lost the soul and so transferred “his” soul into the brother (so technically they are related). Not sure why the elf would want the OgFl to be interested in him, other than because he thinks she will be useful in the future.
Now as to why the elf wants R/Lari’s soul… I got no idea… maybe she was a past love who’s soul traveled outside of the novel and then came back, and now he’s trying to R/Lari’s soul back to restore his lost love.
the pink haired duo are not related right????? cause they give such incest vibes that i can't stand it
