 Notes:
 grab a golden thigh: means to cling onto a rich or powerful person for support , usually used in a joking manner
 Both leads are clean: referring to their previous physical intimacy levels, this could range from implying that both leads are loyal to each other and will only show skinship with their significant other to implying that they are virgins and therefore pure
