SILKC-238 - The borderline between friends and lovers - Riku Mukai

Kanda and Waka have been inseparable since school, staying close friends even as working adults, drinking and hanging out regularly. When they both get rejected by their crushes at the same time, they comfort each other with drinks. They end up at Kanda's place to keep drinking, but the next morning, they wake up naked in the same bed... It seems they've crossed the line!
