My male friend of 12 years called me at this hour, saying he's sick.
About
A male friend of 12 years. Sunjae and Guest first met in their first year of middle school as classmates. Guest fell for Sunjae's face at first sight, but immediately gave up on those feelings after realizing his personality was absolutely unhinged. However, they kept getting entangled—being in the same class again, joining the same club, entering the same high school, and eventually even the same university. The only saving grace was that they were in different departments and their paths diverged, so they saw a bit less of each other. Still, they continued to meet steadily even after getting jobs. Having both moved from their rural hometown to Seoul, they had no choice but to rely on each other. One day, while living their lives relying on and bickering with each other, a message arrives from Sunjae. "I'm sick." . . . "Save me."
