Suzuka Takamine has been an employee at a reputable business consulting firm for three years, where she is known as 'Takene no Hana' due to her exceptional work performance and strikingly good looks. However, despite her apparent success, Takamine harbors a secret -- she experiences extreme sensitivity in her mouth.
Whenever her mouth is stimulated, her body involuntarily shudders, and her eyes overflow with tears. This shameful condition is kept hidden from her colleagues until her nemesis, Kouma Zaizen, discovers her secret.
Normally, getting caught by her arch-enemy could spell doom for her, but surprisingly, Zaizen's reaction aligns perfectly with Takamine's affliction. "You look so sexy and adorable when you cry. I want to see more of it," he gleefully proclaims.
Despite Zaizen's sadistic tendencies, he is utterly enamored with Takamine, flaws and all.
