Hyouka Wang has arrived at the shared house Familia—a raunchy, dangerous battleground of love where plots, schemes, and seduction lurk around every corner threatening to trap the world's most elite spies. She’s a cosplaying beauty, social media superstar...and a spy. She gets right to work, attempting to ensnare Hayato by dressing up as his beloved childhood heroine. But Seraphy won’t go down without a fight and enters the fray with a cosplay of her own! This kicks off a shared-house Halloween cosplay competition, and Hayato has to take their measurements. With such sweet temptations laid before him, will he be able to maintain his composure...?

From clumsy-yet-cold Seraphy, to freewheeling and voluptuous Maria, to immature and mischievous Emily, can first-class secret agent Hayato Kiriyama endure the amorous advances of the three alluring rival spies he’s rooming with?

As a child, Hayato promised to marry his first love, Seraphy. Fifteen yeers later, he has become one of the world’s greatest spies, all while never falling for the temptations of enemy agents. A mission to expose rival operatives turns chaotic when Hayato reunites with Seraphy, and each realizes the other is a spy. Now the pair must live together, torn between love and duty. The question is…who will break first?
