sequelize: Getting nested object as join (one to one) query output

I have written a query where I am using join, I am expecting a flat object (as it is one to one relation and I am using required = true), but instead I am getting nested object.

[{"id":2,"name":"test-1","tutor":{"gender":"M","about_me":"about me"}}]

when I am using raw = true. I am getting:

[{"id":2,"name":"test-1","tutor.gender":"M","tutor.about_me":"about me"}]

Is there any way I can get my output as flat object in seqlize?

Expected output:

[{"id":2,"name":"test-1","gender":"M","about_me":"about me"}]
