Hello, I need help finding this manga. I can't remember it clearly but it's a yaoi manga and the uke is a guy who works as a host but he is new and unpopular and like his only customer is the seme who is rich. The seme is obsessive over the uke, and I remember he imprisoned the uke and like at the end of the story the uke now wears a choker that has a small camera in it, but the uke doesn't know, so the seme can always know where he is. There is also a side couple of a new guy who become a host. The new guy is like a college student, I think and he wasp laced under the tutelage of the top host and like they have like this "host training." That's all I remember. Please help me find it.
