So how did Gendou win Yui's heart, you ask?

Well, with some serious courting,
A disco house...
Smooth music playin' in the background...
and of course...
Some killer disco moves.

Yui: (dreamily sighs). Oh Gendou...them shakin' body moves are just soooooo groooovy and oh sooooo far out (dreamily sighs again). Gendou: Eat this, John Travolta. Grease, er...I mean Gehirn, here i come!
