'Lately I've been having nightmares again...'

Haruka Yashiro suffers from insomnia after changing jobs. One reason is that he has been reunited with Isshiki, the source of his black history. As a sleep aid, Yashiro repeatedly had one-night stands with men. One day, Isshiki saves him from a quarrel and for some reason, they end up sleeping together. That night, the demon king Thomas, who looks exactly like Isshiki, appears in his dream, He is favoured by him with extreme sweetness! In reality, he is a salty person. The gap between dream and reality is a bit of a struggle.
