Hi. I'm trying to find a yaoi manga that starts out with the main character, a famous actor woke up with a young man holding a cat. That young man turned out to be his kouhai from the same agency, who then became his substitute manager. The kouhai had to quit his previous agency because of an affair with the boss. The kouhai loved the main character because he saved him from drowning when he was little.
One more thing, the kouhai jumped onto train tracks to get a box he thought contained an abandoned kitty.

Sorry for the long-winded description. And sorry if I posted in the wrong section. Thanks in advance.
