The War (ChanSoo)

Alternate Title: We Can't Go To Hell (if we're already there) [you can find this fic under this title on ao3]

A North Korean surgeon, Do Kyungsoo found a wounded South Korean soldier washed up shore behind his house. Against his better judgement, Kyungsoo saved the soldier's life and nursed him back to health, and promised to report the incident once the soldier recovered. But as days passed and the soldier made himself comfortable in Kyungsoo's house, Kyungsoo grew reluctant day by day to hand the man in, as he was sure to be killed once in the hands of the government.

In a world that did not fit him, caught in a war that he did not believe in, how could Do Kyungsoo discover a piece of himself in the arms of the enemy?
