Ohhh. Apologies, I guess it isn't in the app yet haha. Thank you for informing! Sunno
No worries! Unfortunately, none of the 18+ content is in the official app. If you use an Android device you can install the Lezhin Plus app from their site, (not available for iOS) otherwise 18+ is only available via the website.
Is this even on the English lezhin site? Idk I'm probably dumb but I can't find it
