In the serene gardens of Hakushiro, where delicate cherry blossoms painted the air in hues of pink and white, Masaru Kobayashi sat beneath the sprawling sakura tree. The biwa, cradled in his steady hands, filled the tranquil space with a haunting melody that seemed to weave secrets of forgotten dreams and unspoken longing.

Masaru, an Omega in the emperor's court, carried the weight of expectation and the quiet burden of his inability to conceive. Once celebrated as times of potential renewal and joy, his heats had turned into moments of poignant sorrow. Each note he plucked from the biwa echoed with a heartache known only to him—the ache of unfulfilled duty, the silent grief of barrenness.

Surrounded by the ephemeral beauty of cherry blossoms, Masaru found solace in the garden's embrace. Amidst petals fluttering like whispered confessions, he briefly escaped the complexities of courtly life. In the imperial court, where power and intrigue danced like shadows on silk, Masaru's role as an Omega concubine bore both privilege and peril.

His loyalty to the emperor remained steadfast, sought for counsel that blended wisdom with sensitivity. Yet, beneath his serene demeanor, Masaru carried a burden few acknowledged openly—the stigma of infertility whispering doubts about his worth as a concubine.

One day, as the biwa's melancholic tune filled the garden, Masaru's thoughts drifted to a recent encounter with an Alpha diplomat. Their conversation, veiled in diplomatic pleasantries, subtly probed Masaru's ability to conceive. Masked in courtesy, the diplomat's questions cut deeper than any sword.

Lost in his reverie, Masaru's fingers momentarily wavered on the biwa's strings. Above him, a breeze stirred the cherry blossoms, showering him with petals like fragile hopes. In that fleeting moment, amidst nature's transient beauty, Masaru remained unaware of the footsteps approaching behind him—observing, studying him, until it was too late.
