Change World, Vol. 1 (Yaoi Manga)

Yosuke had a crush on Arimura— an upperclassman from his high school baseball team—for years before he finally confessed his feelings. And even after a year of being his boyfriend, every day still feels like a dream. But after Yosuke is hit on by a work colleague who he doesn’t realize is Arimura’s former college upperclassman, the subsequent reunion of Arimura and his classmate casts a shadow over Yosuke’s dream relationship.
