Yes and when they ask how many 1ccs you have it means how many boys have you groomed into transitioning.
A 2hu is a target that has entered "stage 2" whatever the fuck that means. When they talk about their favorite 2hus what they really mean is which one of these kids gets you the horniest while you're manipulating and grooming them. This is the part where one of them who is a trusted friend of the target asks for their address to send hrt in the mail, and as soon as they have the address the entire crew starts using it for blackmailing.
