The situation might have been funny if it were happening to somebody else. Back in Battle City, Otogi and Honda's feud might have been termed, "cute"-if it weren't over his little sister.
"Shizuka will definitely give ME chocolates," declared Honda.
Otogi smirked. "Sure, sure-friendship chocolates. You are, after all, her beloved older brother's best friend. But," he added, gesturing to himself, "what girl would want someone like you when someone like me is available?"
Honda growled. "Someone like me? Someone like you? What do you mean by that?"
Otogi ran a disdainful eye over his romantic rival. "Well, when it comes to looks, you just can't compare the two of us. And in addition to that, being the inventor of Dungeon Dice Monsters means I'm a lot more interesting than you are-and fairly wealthy, as well."
"Feh. Your game is just a rip-off of Duel Monsters, and Shizuka's not shallow enough to decide based on looks or money. I'm twice the man you are, pretty-boy."
"Oh please. You say I'm the one calling her shallow, and then you bring outdated gender role standards into it. Real smooth."
Jonouchi frowned. He didn't like it that two of his friends liked his little sister like that (if he had his way, she wouldn't be dating until college at the earliest), but at this point there wasn't much he could do about it. It had been going on too long. It would have been better to nip the whole thing in the bud, but he had been a little preoccupied during Battle City, what with Marik and his Ghouls.
He coughed to catch their attention. "Guys, I find it hard to believe that after knowing her for as long as you have, you can honestly think she's going to make the first move."
"But it's Valentine's Day next week!" protested Honda. "That's supposed to be the day girls declare their love!"
"And you'll both probably receive friendship chocolate from her."
"Well, what do you suggest then?" huffed Otogi.
Jonouchi leaned in and lowered his voice. "How about the two of you make-her-chocolates?"
His sister's admirers looked at him blankly. "Weren't you just calling traditional gender roles outdated, Otogi? I'm kinda sick of watching you two fight over my sister like dogs over a bone. So! Both of you make my sister chocolate-and I do mean make, not buy-and afterwards, I'll ask her which one she liked best. Whichever it is, I'll set her up on a date with the giver."
The verbal combatants froze, not believing their luck. To actually have Jonouchi on their side was an advantage neither of them had thought possible, one neither wanted to lose the chance at.
"Deal!" the two shouted, and ran from the room to make preparations, arguing as they went over who would be victorious this time.
After waiting a moment to make sure they were really gone, Jonouchi sighed. "Coast's clear."
A closet door opened and his little sister came out. "They agreed! I wasn't sure they would."
Jonouchi chuckled. "You know they could never resist the opportunity to compete over you. Even something as ridiculous as a chocolate-making contest."
Shizuka giggled. "Yeah. This is going to be so much fun."
"You know it would save both of us a lot of time and energy if you just picked one of them, right?"
"Well, yeah, but that wouldn't be nearly as much fun."
