@Straw how are you surprised? The fact that he actually likes women but is just super shy and awkward around them and therefore starts blushing all over has been made clear in previous chapters. It wasn't even his idea to have only handsome men around him.
@Nightfury Blizzard i also thought he was a gay,. I found out that he is not when he blushed at the maid girl from previous chapters , i guess in the cell.
