Yuuri is the owner of a small estate in the countryside. When a new maid named Lilith suddenly appears in his life, he is determined to find out the truth about her. Although her identity and purpose are unknown, she works unnaturally hard and her skills at cooking and laundry are so perfect it's almost scary. In addition, her purple eyes... It's like they're about to take you in.

He thinks she's so incredibly mysterious that she must be up to something. And he’s so suspicious that he can't focus on anything else, which is a problem.

This is a story about a lonely boy and a mysterious maid developing a bond little by little.
