I honestly think that this song is about a high ranking business man (a CEO for example) falling in love with a prostitute. Hence "Your love is a crooked pyramid scheme" because he is in love with her, but she is just using him for money. This also explains the line "We should have left our love in the gutter where we found it", suggesting that it was never real love. Also, the lines "Your only crime is that you got caught" and "Lock you up inside" suggest that she was caught and sent to jail. This also validates Big Sean's rap about a girl and that he is "addicted to her".
