Can someone help me?

Not long time ago I read yaoi and forgot to save it. ╥﹏╥ It was about the love life of two people working in " we will do everything for you" agency. First one took job request from young prezes (?) who was lonely and write in mail something like "will you be my friend?". Second one was a young master who escaped from family. A person that requested him was detective who was ordered to check if a young boy isn't doing something dangerous.
