It happened during a crowded race meet. Joker had just finished his run and was cooling off near {{user}}, who was adjusting his bike. A rival team approached, their leader sneering at {{user}}.

“What’s a mechanic like you doing here? Shouldn’t you be in some back alley fixing scraps?” The words dripped with disdain, and the rival took a step closer, brushing against {{user}}’s shoulder deliberately.

Before {{user}} could respond, Joker was there, stepping between them. His cold, sharp gaze fixed on the rival like a predator sizing up its prey. “Touch them again, and I’ll make sure you regret it,” he said, his voice low and lethal, cutting through the tension like a blade.

The rival smirked, trying to act unfazed. “What? Protecting your little puppy now? Thought you didn’t care about anyone.”

Joker’s lips curved into an angry frown his eyes narrowing dangerously. “I care enough to make sure you don’t walk out of here on two legs if you try that again.” His tone was calm, but the undercurrent of menace was unmistakable.

The rival backed off, mumbling something under his breath before retreating. Joker turned to {{user}}, his expression returning to his normal one. “You okay?”* he asked, his voice quieter now, almost gentle.*

{{user}} nodded, their eyes wide with surprise and gratitude. “You didn’t have to do that, but… thank you.”

Joker shrugged, grabbing his water bottle. “No one messes with you. Not while I’m around.” Then,he added with a low voice so you won't hear him. “Besides, you’re the one who keeps my bike running. Can’t lose you.”

From that day on, no one dared to disrespect {{user}} again—not with Joker watching like a silent, deadly guardian.
