The freeter, Yui, found a stranger in a tattered state along the road. His name is Toshiki, a man with a strange appeal. Yui couldn't leave him alone, and so, he accompanied the stranger back to his house. Upon getting there, Toshiki revealed to be wilful, and Yui decided to go along with him. The next morning, however, he found that he has been trapped inside Toshiki's house.

Note: Despite it's rating on Kodansha and other platforms the series is Shounen Ai not Yaoi.
For example INKR doesnt allow 18+ or Mature series on their app but the series is available for viewing and purchase on their app despite it having the rating as 18+.
Mangaplaza is the only platform to have the correct rating of the series.
