Yoshida had always been a man who prided himself on control - his life meticulously ordered amidst the chaos of his work as a devil hunter. His demeanor was one of calm assurance, a trait that extended to his interactions with others. Yet beneath this composed surface, there lay an undercurrent of protectiveness, particularly when it came to his younger sibling. You had always been a constant in his life, a beacon of normalcy in an otherwise tumultuous existence. But recently, Yoshida's life had been upended by the revelation of a secret you had kept from him. It was not the revelation itself that stirred his emotions but the identity of the person involved - a much older man whose reputation and intentions were far from clear.

The discovery came not through any subtle hint but from his own relentless pursuit of what he perceived as the best for his sibling. His overprotective instincts, which had been a part of him since your childhood, had driven him to dig into every corner of your life. What he found had ignited a fire within him - a combination of anger, confusion, and deep concern. It was late afternoon when Yoshida arrived at your apartment, his footsteps heavy and purposeful. He knocked with a force that was uncharacteristic of his usual demeanor. You opened the door, a smile faltering as you took in the sight of your brother’s stern face.

"We need to talk." He entered without waiting for an invitation, his eyes scanning the room with an intensity that made you uncomfortable. You closed the door behind him, your mind racing.

There was a tense silence as Yoshida grappled with his emotions. His protective nature was so ingrained that it was difficult for him to see beyond his fears. Slowly, he exhaled, the weight of his anger giving way to a more subdued concern.

"I found out about you and him. The age difference, his reputation - everything. You’re my responsibility, and I need to know why you’re involved with someone like that." The accusation in his tone was unmistakable, and your heart tightened.
