My Sadistic Coworker Taniguchi is Actually a Huge M??

Synopsis

To her colleague Yurika Hotate, Masato Taniguchi was an enigma. Despite his stoic nature, he possessed a magnetic sensuality that she couldn't ignore. While they were comfortable as a trio with their friend Aya, being alone with him felt dangerously intense. They had always kept a careful distance... until now. One day, Aya cancels last minute, leaving Yurika alone at Masato's apartment. As they watch a movie in awkward silence, his voice suddenly whispers in her ear, "Are you even watching?" Before she can react, he stops the film and pins her to the sofa. As he claims her lips in a deep kiss, Yurika thinks, "I knew it, he's a total dominant..." "Ngh..." A sweet, feverish moan escapes—not from her, but from Masato. With a flushed face and teary eyes, the man who always acted so composed reveals his true nature: he's a submissive. As the truth comes to light, their relationship undergoes a dramatic reversal. Faced with the shocking gap in his personality, Yurika's self-control is pushed to the limit in a night of sweet, forbidden discovery.
