Pride Goes Before a Fall

Esper Seo Kang, wants only pretty and handsome Guides to guide him. Later, he starts suffering from a lack of guiding. He's at the point where he'd rather go insane than be guided by someone whose looks don't suit his sexuality. U Tae-San, the Center's eccentric researcher, appears before Seo Kang with a disturbing proposal.

"I've got a nice body, why don't we find out if I can get you hard or not."
