This is basically a story of domestic abuse and I hate to say it - but very little character development. (Spoilers) You have one guy basically controlling the actions of the other guy and while there is attraction between the two of them, this is a very unhealthy relationship. Watching this you keep hoping that the abuser will change his ways or the victim will stand up for himself, but neither happens. On the last episode it is just another day in very sad cycle that they are in and neither is any better off than when the series started.
