Help with Character Design!

ok so i have an anime idea thats about a boy whos cursed and desperately looks for an answear so he goes to an exercist, and she helps him but for a price. hes cursed becuz so many ghosts and spirits r attracted to him, so she uses him as bait to track alot of sprits in one place. so they bind there souls to make the contract official and now he can see ghosts too. so i was wondering how i sood make the girl look, i want long hair, but idk the style. shes a tsundere who rarely smiles but isnt gothy. the boys abit nerdy and gets pushed around often but not over the top, maybe glasses. so ur ideas?

need abit more description like clothes and such XD and what about the gguuy D: he feels so sad.... guy:TT3TT
