Shinyuu to Kozukuri suru Koto ni Narimashita.

Hanataro is the young president of a major corporation, burdened by relentless pressure from those around him to produce an heir. Despite their persistent demands, he possesses neither the desire nor the time to pursue marriage or start a traditional family. Just as the expectations become overwhelming, Kaname—his trusted secretary and closest friend—steps forward with an unexpected and life-altering proposal: he offers to carry the child himself. Determined to see his promise through, Kaname immediately begins taking a specialized medication designed to allow men to conceive. However, this experimental drug comes with unforeseen consequences. As his body adjusts to the treatment, Kaname begins experiencing an unrelenting tingling sensation that refuses to subside, introducing a deeply intimate complication to their unconventional arrangement. What began as a practical solution to Hanataro’s predicament soon evolves into something far more complex, blurring the boundaries between professional duty, lifelong friendship, and unexpected physical vulnerability.
