I’m not sure, maybe someone will prove me wrong but as far as I know, usually(if the official chapters are uploaded here from payed resources) the last chapters are not free in the end of the season. So when the next season is starting the official platform releases the last chapters of previous season of the manhwa for free. Probably the next season is starting now so they were able to get this episode here. As legally tge manhwa is not supposes to be here, probably out of respect to the author the chapters were uploaded here only after they were available for free on the original website (just my theory, sorry I tried to explain but probably made it more complicated )
No updates for 5 months, and NOW it’s the end of season 2? What tha fuck. #－.－)
