Maou-sama, Kekkon desu!

Hino Komako is a marriage counselor who'd given up on her own happiness, until she was suddenly transported to another world! *“Could it be... me with this hottie!?”* Komako's heart soared at the sight of the handsome Demon Lord waiting for her, until he asked her to help with matchmaking instead!? But the Demon Lord seems to have a secret he won't tell Komako…? A fresh take of an isekai romantic comedy.
