Maybe It's Sad(2004)

After graduating from university, Satoshi Takagi joined the advertising agency he had always dreamed of, and started his working life with great enthusiasm. Satoshi has a boyfriend who is more than a friend but less than a lover, but even when she tries to talk to him about the company, he only wants Satoshi's body and won't listen at all. “Am I just a body?” The distance between him and Satoshi has widened a little. Despite this, Satoshi did his best at work. He was actually starting to be attracted to his boss, Furukawa. However, Furukawa is a straight man who is dating Satoshi's colleague, an office lady. Although it is a dream that cannot come true after all, my feelings for Furukawa, who does his job in a cool manner, grows stronger every day.
