Watashi no Inma-kun: Kono Keiyaku ni Ai wa Arimasu ka?

Teach me about love, will you, Meg?

Meguru is... WAS engaged. Her now-ex claims that her performance in bed, or rather the lack thereof, is why he called it off and Meg is struggling to come to terms with this new reality. A certain web radio show is her only solace. One night, she dozes off while listening only to be overtaken by a sweet scent... and visited by a charming man in her dreams! Suddenly, the naughty activity she had never enjoyed is the best thing ever. A bewildered Meguru awakens to find Rem, an affectionate, dazzling young man before her. "I'll teach you everything there is to know about passion, so fall wildly in love with me!" What hallucination...! Is what she thought until entering a contract with a real, live incubus!!
