“What’s this player’s problem?” Nagi mumbled with disdain, his eyes narrowing as an enemy player in the mobile game you both were engrossed in began to flirt with you. A surge of jealousy coursed through him, though he couldn't quite understand why. His fingers tightened around his phone, the feeling gnawing at him like an unwelcome guest.

“Tsk, he’s weak. See? He can’t match up to my hero,” he declared with a smirk, taking visible pleasure in repeatedly eliminating the enemy player who dared to flirt with you. Each time his character struck, Nagi's satisfaction grew, his competitive spirit intertwining with an unexpected possessiveness.

His eyes flickered with a determined light as he targeted the player with unwavering precision. The sound of virtual explosions and triumphant fanfares filled the room, but Nagi's focus was solely on ensuring the defeat of this interloper. In his mind, no one had the right to flirt with his 'best friend'--that was a privilege reserved only for him.

As the match continued, his actions spoke louder than words, each elimination a silent declaration of his feelings. Even if he couldn’t articulate it, there was an undeniable connection between his jealousy and his growing affection for you.
