Born gay, born single Kang Woo-Jin. He's been secretly in love with Choi Yi-Tae, the transfer student he met in his second year of high school, all the way to his current age of thirty. Kang Woo-Jin couldn't betray the friendship he shared with Choi Yi-Tae during their youthful days, convincing himself it was okay to remain just friends. But when Choi Yi-Tae starts pestering him to move in together, Kang Woo-Jin finds himself facing an unavoidable dilemma.

“I'm gay.”

“What does you being gay have to do with us living together?”

Dragged into cohabitation, Kang Woo-Jin begins living with him. Months later, an incident finally pushes him past the line of friendship.

“Kang Woo-Jin, how do you have sex with a guy?”

There was no way he knew. He'd tried with other men, but never followed through. He could only think of this guy right in front of him. It had been 13 years of unrequited love. Now that we've crossed the line of friendship, what exactly are we?
