Stay by My Side After the Rain Vol. 1 (manga)

Kanade is an office worker who’s unfulfilled in life... and keeps the fact that he’s gay a secret. Everything changes when he reunites with an old classmate from high school: Mashiro, the boy Kanade secretly liked back in his youth.

Mashiro’s arrival seems to bring new sunlight to Kanade’s dreary life. As they get to know each other again as adults, could this be Kanade’s chance to find love with the one who got away?
