So you've just admitted that there's a Fanbox that some other scanlator will jump on in a heartbeat once they find whatever third party leaker had them?
It sucks when a story is like that. Far better to have the tension suggestive story as a lead up to their R18+ story of totally doing it. And in that version have some parts that can be posted separate to talk around the naughty and show how their lives are.
I'm NGL there being an official R18 version ruins the magic. The series is more cute than anything, so I can't take them fucking any more seriously than I can smashing two plushies together and calling it sex.
