The Clumsy Succubus and the Cursed Loner Adventurer

Theo is a solo adventurer cursed with the "loner" curse, which makes it impossible for him to form a party with anyone. While visiting the remote frontier town of Disbule, where succubi are rumored to be attacking the locals, he gathers information at a tavern. There, he meets Lilya, a young woman dressed in elegant, noble attire that seems completely out of place. After Theo rescues her from a group of drunken men harassing her, she offers to repay him by saying, "I'll... do something naughty for you," and starts taking off her clothes...!?
