Yuri can't just catch a break.
There he was, chilling after his most recent victory, when Karin pirouettes in, chipper about the new man who swept her off her feet and turned her head over heels that afternoon, with his resplendent looks and perfect manners. Whine whine whine why can't Yuri be like that complain complain complain she bets he'd make dinner for her whine whine whine why can't Yuri ever help her and Alice out complain complain complain the clothes are stacking up in the washbin moan moan moan aaaaaaaaaaaaaaaaah
In the end, Yuri caved in and bought her a diamond ring - because nothing else says "shut up" as well as expensive things. Of course, Karin never brought up the name of this mysterious fellow, which is perhaps just as well.
He did have cute tailfeathers, though.
