Hana -a last flower- Lyrics - Aku no Hana belongs to the anime Aku no Hana, take a look at the argument:

Takao Kasuga, a high school student with an undying passion for poetry, finds himself captivated by the works of Charles Baudelaire. So much so, that he adorns his room with a prominent portrait of the renowned poet. However, fate plays a mischievous hand when Takao carelessly forgets his cherished copy of "The Flowers of Evil" in the classroom, leading to an unforeseen turn of events. In a bizarre turn of events, Takao surreptitiously pilfers the sports attire belonging to none other than Nanako Saeki, a paragon of virtue and excellence. To Takao, Nanako is not just a mere classmate, but a muse and a femme fatale who unknowingly entrances him. Overwhelmed by guilt and self-reproach, Takao finds himself trapped in a web of his own making when he discovers that Sawa Nakamura, a classmate largely shunned by society, is privy to his dark secret. Exploiting this newfound leverage, Sawa ruthlessly blackmails Takao, coercing him into partaking in her twisted, disturbing fantasies. Failure to comply would mean facing the dire consequences of having his unsavory transgressions exposed to the world. Bound by fear and trapped within an ever-escalating cycle of haunting experiences, Takao teeters on the precipice of despair as he seeks redemption for his sins and liberation from Sawa's suffocating grasp. Will Takao summon the strength to break free from the thorny clutches of his tormentor and seek redemption for his actions? Or will his life be forever marred by the darkness lurking within "The Flowers of Evil"?
