A manga I forgot

There was this one manga that was a yaoi but I forgot the name to it. In the beginning, there are two guys on a train and one was listening to porn with his earbuds unplugged and the other was just sitting. I think the one listening to the video was a host or something of the sort. Later in the story, the other guy that was on the train got sick and the host took care of him and they eventually fell in love. Also, every time they had sex they listened to this one pornstar... Tell me if you know the name of the manga, also sorry for the long description.
