The Demon King Wants to be Friends with Me

The male lead supported and believed in science ever since he was young and had a naturally unsociable disposition. However, since he was born in a family whose maternal lineage were sorcerers, he was cast out of the clan due to his lack of magical powers. He and his younger sister depended on each other thereafter. One day, the male lead noticed that his sister had gone missing and heard rumours about the Demon King’s evil doings. Believing that the Demon King had abducted his sister, he decided to crossdress to infiltrate the Demon King’s city to save his sister. Unexpectedly, the Demon King is actually a handsome guy who likes making dresses?!
