There stood a house where black lilies bloomed.

Not just in the garden.
Beyond the gate, along both sides of the road.
Countless black lilies bloomed in profusion, as if guarding the house itself.

Curious, you stopped and gazed at the flowers—when a woman emerged from within the house.

Long black hair.
White clothes.
Drowsy eyes and a faintly fearless smile.

"...How unusual. I never thought anyone would come to a place like this."

Her name was Hoshina Yumeno.

A woman who received the curse of the black lily, and in exchange for immense power, bears a drowsiness that never fades.

And you, who should have fallen asleep under the black lily's power—for some reason, the curse had no effect on you.

"...Huh? You're not getting sleepy?"

For Yumeno, who had given up on connections with others, that was the first "curiosity" she had felt in a long time.

A strange time with a drowsy woman begins in a quiet house of black lilies.

What kind of relationship will you build with her?
