Cuiv is not IEE, he doesnt even value Si or Fi. And an IEE would never present himself as Cuiv does. Like ever. Not even in forums. Not to talk about his wardrobe
. IEEs 3 want to look charming and attractive, EIEs want to make an impact.
To me he's Si PoLR (experiencing Si just in his particular way, regardless what everybody else think or prefer and he feels pretty hurt by Si normativity in society), and his expression could perfectly fit in EIE theatricality (Fe) imo (it has nothing to do with his voice irl, lol).
He also seems fitting into aggressor/victim style I could not imagine him in childlike/caregiver style (I don't think he could imagine himself in that style neither).
I think he's EIE Ni 3w4 8w7 and maybe 6w5. Sx/sp or sp/sx.
