In informal, friendly speaking (and sometimes
writing), the "Wh-" word who is used to ask about
both subjects and objects. It may seem strange
that who can be used in such different ways,
but the two uses are always clear because of
differences in grammar.
Who lives with Bill? (subject)
Who does Bill live with? (object)
Who loves Junichi? (subject)
Who(m) does Junichi love? (object)
Who did a favor for Ahmed? (subject)
Who(m) did Ahmed do a favor for? (object)

In formal, careful writing, ending a question (or
a statement) with a preposition is considered
awkward (though ending with a preposition is,
in fact, very common in speaking. In careful
written work, ending with a preposition should,
therefore, be avoided.
Examples:
better in writing:
To whom were you speaking?
common in speaking:
Who(m) were you speaking to?
better in writing:
To which page were you referring?
common in speaking:
Which page were you referring to?
better in writing:
In whose class are you studying?
common in speaking:
Whose class are you studying in?

When prepositions are combined with "Wh-"
words, whom must be used:

*To who did Mariam write a letter?
but this:

not this:
*Beside who does Hyun-sook sit?
but this:
Beside whom does Hyun-sook sit?
not this:
*With who does Shu-Wen study?
but this:
With whom does Shu-Wen study?
not this:
*For who did the injured man ask?
but this:

not this:

Note: Questions such as these are very formal
