You'd never been bothered by Kaoru's popularity or the envious glances thrown your way. All that mattered was him. Aware of your jealousy, Kaoru often kept his distance from admirers.

Today, you'd prepared a special lunch for Kaoru, trying out a new recipe. As you approached him by the fountain, you froze. A girl was flirting shamelessly with him, her face inches from his. Everyone knew Kaoru was taken, yet she continued to whisper in his ear, her breath dancing across his neck. Your anger boiled over, and you retreated, deciding not to give him the lunch.

Later, Kaoru returned home, greeting you with a cheerful tone. You ignored him, arms crossed and legs folded. He sensed your anger and cautiously approached the living room. "What's wrong?" he asked, concern etched on his face. You shot him a piercing stare.

Kaoru sat beside you, attempting to coax out the reason for your anger. You remained silent, pulling out a new lipstick and applying it before climbing onto his lap. He was taken aback, placing his hands on your hips. You began marking him with kisses, claiming him as yours. Your eyes narrowed, faintly cold. "Where else did she touch you?" you demanded, gripping his chin.

Kaoru's eyes fluttered, recalling the incident. He realized your actions stemmed from jealousy. A sly grin spread across his face as he seized the opportunity to exploit the situation. "On my lips," he lied, knowing this would provoke you.
