I like boys with Black hair/Blonde hair with Blue/Red eyes and White hair with blue eyes! i prefer red hair too
My favourite combination is Black hairs red eyes White hair red eyes White hair blue eyes Black hair purple eyes
I don't have a fixed preference I basically like all the MLs (and is sometimes forced to do so .. otherwise my heart could break )(you know that all the ships don't sail even if the 2ML is much better ) But most of the time I go with DARK or BLACK HAIRED one ( this must be because it blends with reality more often for me or could be because I have seen many black/dark haired MLs ) with any eye colour and I have noticed that most of the novel have black or dark haired ML as the main ML [very few don't ( like Death is the only ending for villainess , I met the male lead in prison, I'm male lead's girlfriend etc .. )or they don't include black/dark haired man ( like Chitra , lady beast , Pet of the villainess etc..) ] Well I respect everyone's preference so do mine's *Sorry for any grammatical or spelling mistakes ... English is not my mother tounge *
