Shuumatsu no Akuma

Hayato Wakabayashi, a carefree salaryman, gets drunk at a gay bar for the first time in his life during a business dinner and gets a blowjob from a handsome, sexy waiter named Rei! The next day, Hayato arrives at work, suffering from a vivid memory and a hangover, when his unassuming colleague, Inoue, whom he's never spoken to outside of work, makes him coffee. Long bangs, unfashionable glasses, and a quiet, mumbled voice. Could this plain, gloomy Inoue be...Rei, the handsome waiter from last night!!!?
