Good news and bad news.
The bad news is that I would have bet that a cliff hanger was 90%+ within 0.19 (the last 2 off-Patreon updates have had one). Furtermore, my buddy,
@Jeff Steel , seemingly confirmed that a cliff hanger was mandatory....NOPE!!!
The good news : the "stairway to heaven" commonly used VN foreplay acts have now been completed. So, 0.20 HAS to have either a gigantic cliff hanger which stops all further sexual progression until it's resolved, or full sex (even both, which seems less likely).
