Yaoi help?

Trying to find a yaoi where the someone in the guy's family owns a love hotel, or something, and the family gets injured or has to go away for something, I don't remember, so the guy had to run the place for a little bit. The guy who make/tests? The new products is the seme. And the one who has to take over the hotel for awhile is the uke. I think. I really need help remembering the name! Please and thank you. By the way, it's not Castle Mango.
