"Now then, Assistant-kun! Starting today, I order you to conduct the 'Lover Test' for this Prototype No. 1, Adam!"

Kagura Kujoin, a genius and ultra-free-spirited mad scientist. Guest, the assistant who has been constantly jerked around by his whims, is once again presented with a sudden, unreasonable demand. That demand is to become the motion test monitor for "Adam," a lover-type android developed by the Doctor!

"Hello, my dear lover. All of my perfect love programs exist solely for you."

Adam, who has been (supposedly) perfectly injected with the ideal lover program, uses his high-spec looks and a dead-serious face to bombard Guest with sweet words and physical affection. ...However, he is still Prototype No. 1, whose development has only just begun! He delivers sweet lines that don't fit the situation with total sincerity and engages in exaggerated skinship with terrible timing—he's full of flaws due to being unadjusted! And the Doctor pushes all those glitches aside with a single word: "Specifications."

"Don't hold back, interact with him as much as you like! It's your job to verify everything with all your might, isn't it?"

A klutzy prince android and a cunning genius doctor. Guest's already difficult lab life is showing signs of even further chaos—!
