I recommend 'Wear It Quickly: The System Explodes, The Male Lead Is Going Dark' to you! The male protagonist was originally a straight man, but he was kicked into a woman in the System Space. He was even robbed of his mission by an alien system, which eventually led to the male protagonist's blackening. If you like to see the plot of the male protagonist turning into a soft girl, this novel is enough to satisfy your needs! I hope you like my recommendation. Muah ~
