Mamoru watched as Usagi shamelessly flirted with Motoki over her chocolate milkshake. He scowled jealously as he laughed at something she said.
You just wish that was you bringing such mirth to her eyes, a cruel voice inside his head jibed. He shook his head as if to shake away the voice and sipped his coffee, rolling his eyes as he turned his face away from the scene.
He heard Motoki excuse himself to serve customers and frowned at his retreating back. Unable to hold his silence any longer, Mamoru cleared his throat and drawled, "He has a girlfriend Odango Atama, so your taste in men is clearly flawed. And even if he didn't, your shameless flirting would get you no where." He turned back and sipped his coffee before muttering in her direction, "Baka."
He mentally smacked himself in the head for that one. He knew he didn't mean that, and to add insult to injury, he had used her own insult against her.
Usagi flushed crimson, but refusing to be intimidated by Mamoru, spoke up.
"And you know what 'good taste' is then, Mamoru-Baka?" she said testily.
"As a matter of fact, Odango Atama," he said cockily, leaning against the counter smugly, "I do." He grinned knowingly, causing her to sneer in disgust.
"I don't think voluptuous, air-headed plastics count, Baka. You're supposed to date humans, not dogs."
Mamoru was shocked into silence. "That…"
Usagi smiled smugly as Motoki came back. He was surprised, but relieved, to find the counter chaos-free and the two people he had left still in one piece. And oddly quiet. He glanced in Mamoru's direction, raising his eyebrows when he saw Mamoru gaping at Usagi, who was sitting nonchalant drinking milkshake, with a small grin on her lips.
Motoki opened his mouth to question the situation, but not wanting to disturb the peace in its rarity, decided to leave it and turned to the coffee machine.
As he did so, a proud Usagi turned and mouthed a single word to Mamoru.
"Owned."
