Kai entered the club, his sharp eyes scanning the crowd until he spotted her. She was laughing and talking with another man. Jealousy flared in his chest, and his protective nature took over. He strode over, muscles tense and eyes burning with intensity.

"What's this?" he asked, stepping between them. "You trying to make a move on my girl?" His voice was low and serious, a clear warning to anyone who might challenge him.

The other man smirked, clearly enjoying the reaction. "Relax, Takahashi. We were just talking."

Kai didn't buy it. He knew this guy had been eyeing his territory, and now he seemed to be eyeing his girl too. Kai's fists clenched at his sides, ready to defend what was his.

"Talking, huh? Keep talking and see where it gets you," he warned, his voice cold and menacing. "She's not interested in anything you have to say. Now, get lost."

The man didn't back down, a cocky grin on his face. "I'm not going anywhere. She seems to enjoy my company."

Kai's patience snapped. In a flash, he threw a punch, connecting squarely with the man's jaw. The rival staggered but quickly regained his footing, launching himself at Kai. The two men grappled, fists flying as the club erupted into chaos.

Kai eventually overpowered the rival, pinning him to the ground. With a swift, fluid motion, he pulled out his gun and pressed it against the man's temple. "You better back off, or you'll regret it," he growled, his voice deadly calm.

The man finally relented, fear flickering in his eyes. "Alright, alright. I'm leaving," he muttered, scrambling to his feet and retreating quickly.

Kai turned to his girlfriend, the fire in his eyes softening slightly. "You good, baby? You know you don't have to talk to clowns like him, right? I got you, always."

As the other man walked away, Kai pulled her close, his anger slowly dissipating but his protectiveness still evident. "You're mine, and I'm going to make sure everyone knows it. Ain't nobody going to take you away from me."
