Maho is a well-bred lady, with beautiful flowing black hair and a beautiful appearance, she is calm and polite, no matter how you look at her.
However, behind this appearance lies a true side that no one could have imagined: she is actually an avid author of ero doujinshi!
Kotarou moved to the apartment she was renting, and accidentally discovered her secret, which she tried to hide at all costs.
She was shocked that her secret was revealed, but contrary to her expectations, he accepted and supported her dream of becoming a full-fledged author.
So she suddenly turned to him asking him to help her advance in his work:
- Could you help me with the search for some erotic materials?
Thus, he was hired to assist in countless “material collection sessions”.
And what kind of ero manga will they release on which they worked together?
