Ryu felt a tumult of emotions flood through him at Yuuki's mention of his father. The innocent plea echoed in his mind, yet it carried a weight that twisted within him. Memories of the night that had reshaped his very existence surged back, igniting a fiery rage. The screams, the chaos, the cold reality of loss flooded his thoughts, pulling him back into that dark abyss.

How could this boy, standing before him in such a vulnerable state, still cling to the notion of safety in his father? The thought alone sent a wave of bitterness coursing through Ryu's veins, as if the mere mention of that name had twisted a knife deeper into old wounds, reopening scars.

"You think he can save you?" Ryu's voice dripped with icy venom, the mask of control he had worn slipping as his anger seeped through. The smirk on his face faded, replaced by an intensity that made the air between them crackle with tension. "Your father is the reason I'm here. He is the root of my suffering… and now, it's your turn to understand the pain he has caused."

Taking a deliberate step closer, Ryu felt a dark satisfaction swell within him as he locked his gaze onto Yuuki’s frightened eyes. The boy’s expression mirrored confusion and terror, and that fear only fueled Ryu's desire for retribution. It was a twisted sense of justice that drove him, but in this moment, all he could think about was forcing Yuuki to face the echoes of loss that had haunted him for so long.

"Tell me," Ryu continued, lowering his voice to a chilling whisper, "how does it feel to be so completely at the mercy of someone like me?" 

He could sense Yuuki’s heartbeat quicken, the tremors running through his body signaling the stark realization of his predicament. The power dynamics had shifted, and Ryu reveled in that realization. It was a bitter irony—the boy was unsuspecting, a pawn in a game that had begun long before his time. Ryu’s breath caught for a moment, and he fought against the surge of conflicting emotions within him.

It was supposed to be simple—a means to an end, a way to exert his control over the memories that haunted him. Yet, standing before Yuuki, he couldn’t ignore the flicker of humanity that stirred within. As much as he wanted Yuuki to feel the pain he felt, there was an undeniable part of him that recognized the boy's innocence.

The room felt charged, the weight of their shared history heavy in the air. Ryu’s stare held firm, a contemplation amid the chaos of his feelings. What was the true cost of his revenge? Would dragging Yuuki into this cycle of pain truly bring him the satisfaction he sought, or would it only deepen his own scars? 

Ryu had always believed that vengeance would provide him peace, but standing before Yuuki, he began to wonder if it would only leave him more fractured. The battle within him raged on, torn between the urge to protect this innocent boy and the relentless need to confront the father who had wronged him so deeply.

With a resigned sigh, Ryu stepped back, giving space yet keeping his eyes firmly locked on Yuuki’s. “The choice is yours,” he stated, his tone softening slightly. “You can continue to hide behind your father’s shadow, or you can face the truth of who you really are.”
