1 year and 5 months since the author released the last chapter of season 1. For whatever reason for the long hiatus I'm hoping that the author has been working on the storyboard, pacing and stuff, so that when the manhwa does finally come out it won't feel like they are pulling out the story out their asses every week.
I read so many manga, manhwa that had a good first season/volumes then to trashy follow up.
