"to the father of the na'arah" (and not to the father of the bogereth).
"and to him shall she be as a wife": We are hereby taught that he must "quaff his bitter cup" — even if she be lame or blind or covered with boils. If there were in her a thing of zimah (obscenity) or if she were not fit to marry into Israel, I might think that he were permitted to keep her as a wife; it is, therefore, written "and to him shall she be as a wife" — (connoting) a woman who is (halachically) fit for him (as a wife).
