If Yuugi can do it, Ruca can do it! ... Is what Yuugi would/will firmly believe, at least.

And pfft, that's adorable. YUUGI IS SHORTER THAN EVERYONE, oh well. XD But yes, good. He wouldn't be super pushy about trying to be Ruca's fake older brother (in fact he'd never put it in those words) but I can imagine him just being, like. Conveniently there if Ruca needs him. >.>
