end of the year ....
Season 3 ended in September-2020 (raw) and new season started recently at right it is ch90 or 91. So I think authors message is for people who has been reading it in korean. Not for English reader. Maybe the translated season 4 come back after month later. I don't think we will wait until the end of 2021.
