Sasha is the deuteragonist of the story.

Despite not looking the part Sasha is Stacy’s manager and her closet friend.

Sasha is incredibly intelligent despite not looking so, she has many connections and is able to get things the average person wouldn’t normally be able to get even through legal methods.

Sasha is however oblivious to Stacy’s past and her real identity, although she has kept her eye on her ever since she “changed”. She’s not an idiot she just really thought she wanted that 180* change in her life.

However when Stacy’s real identity is essentially revealed Sasha is completely heartbroken and her trust is gone with “Stacy”. Furthermore, she discovers the truth about what happened to the real Stacy.

This of course breaks the two's friendship with only Sasha being affected in the long run because Stacy simply doesn’t care.

Essentially Sasha begins to side with Estelle and wishes the worst upon “Stacy” however she can’t help but feel a little guilt for doing so because whoever this person is, she still had a connection with them.
