Ai da, Koi dano Shouhosen

Destiny is written in the body. Rinto Kiriya is a Beta who leads a quiet, structured life working as a pharmacist at his own dispensing pharmacy. His routine is unexpectedly disrupted when he receives an unusual professional request from a major entertainment agency. They ask him to prescribe specialized inhibitors for one of their clients: Shiro Sato, an Alpha and a prominent member of the wildly popular band Welt. What begins as a standard medical consultation quickly spirals into something far more volatile. The moment Rinto comes face-to-face with Shiro, everything he understands about his own biology shatters. Despite being a Beta—a designation that should theoretically render him immune to such reactions—he is suddenly overwhelmed by an intense, undeniable surge of lust. Unable to resist the powerful pull, Rinto collapses directly into Shiro’s embrace. This unforeseen physical response forces the reserved pharmacist to confront a bewildering new reality, blurring the boundaries between his clinical profession and a deeply primal attraction he never knew he possessed.
