The Night is Rose-Colored, My Way(1989)

Overview

A pair of robbers break into a loan shark company. I thought they were breaking in for money, but not only that, but they started raping and toying with male employees who were tied up and deprived of their freedom. In fact, the robber was a gay man who once came to borrow money from a loan shark, but he was turned down and made fun of because he couldn't lend money to a homosexual who works at a gay bar.
