something to protect (слэш)

Yoon Soo-Hyun is just minutes too late to prevent Kim Ga-On from attacking Do Yung-Choon outside the courthouse.
Kim Ga-On spends three years in prison and is released during the worst of the economic crisis. Unable to find “honest” work, he gets a job as an escort.
Kang Yo-Han hates people, especially in large groups, where they crowd him and make suggestive comments. An escort, he finds, makes an excellent shield against some of the more persistent and inappropriate people he’s forced to socialize with. Escorts follow rules and expectations, at least until he meets Kim Ga-On, who burns with rage underneath his polite exterior and keeps insulting the Foundation’s Directors in a way that’s just subtle enough that they don’t notice – but Kang Yo-Han does, and instantly senses a kindred spirit.
