However, in this case: 'Am I the one WHOM you want?' Cf. Leonard Bernstein's Wonderful Town, 'One hundred ways to lose a man': http://www.metrolyrics.com/one-hundred-easy-ways-lyrics-wonderful-town.html or https://www.youtube.com/watch?v=uNDRmCsm3RQ
I have a question,
"Preposition + Wie: refers back to a person." that means you need to have a preposition already in the sentence? or you can add one forcefully.
If it need a preposition in the sentence, fine I will use "die"for sure
But if you can add a preposition to use "van wie" it will be "Ben ik degene van wie je wilt"?
