Shizuku has no interest in romance, as her work and hobbies are enough to make her life fulfilling. Her mother wants her to marry, though, and at her insistence, Shizuku concedes to meeting Takaharu, a handsome and elite researcher, just to see if they might be a good match. Then, at their very first meeting, Takaharu pops the question out of nowhere...! He also gives a very well-reasoned pitch on how the arrangement would benefit them both, which Shizuku finds so persuasive that she accepts his proposal on the spot.

Despite starting on such a mercenary note, their newlywed life sees Shizuku developing deeper feelings for the calm and gentle Takaharu. At the same time, though, the way he always maintains a polite distance and never even tries to touch her leaves Shizuku full of doubt...!!

Meanwhile, Takaharu is closely guarding certain hidden feelings of his own...

Letting the right moment for a wedding night slip past them was just the start of the hectic, heart-pounding romance for this adorably unfortunate fledgling couple.
