It's nice to see this manhwa getting the top spot again on Lezh!n, meaning people are purchasing again. Uploader delaying their posting here for at least a day do really help the author. Thank you uploader for your consideration.
That being said, Ep85 implies that Grandpa Go really is a villain in this story. I thought by being nice to Jooin, he was showing that he was respecting Yahwi's choice. But no, it was actually to warn Yahwi.
