Need help finding the title

I'm trying to find a yaoi series I read quite sometime ago. The story goes like this.

The protagonist has an unrequited love for his friend who's getting married soon. So he went to a gay bar to chill, and another man, named Kou picked him up. Turns out he was his company president. Kou was so sweet to the protagonist but it was all a game. He was a player and planned to ditch the protagonist after capturing his heart. Then, the protagonist found out and transferred office and Kou tried to chase him back.
