Himawari wa Yoru ni Saku

Storyline & Plot Overview

Norihito and Asumi Hisato were once the picture of a happy couple, until a fatal professional blunder by Norihito cost his company millions of dollars. On the brink of bankruptcy and facing potential imprisonment, a cruel “lifeline” appeared. The company president made an implicit proposal: Asumi must become his private secretary to “deduct” her husband’s massive debt.

Trusting in the president’s supposed kindness and fueled by her love for Norihito, Asumi plunged into her new role, unaware she was walking into a meticulously crafted tiger’s den. From late-night overtime to private business trips, the president gradually stripped away her modest exterior, turning Asumi’s gratitude into a tool for sexual manipulation.

Asumi—the most vibrant sunflower—begins to “bloom” in the most humiliating way within the darkness of luxury VIP suites. To protect her husband’s future, she accepts every depraved demand, thanking the president in the “only way” he desires: with her very own body.
