We are definitely in "cliff-hanger" mode with this VN, and I can't blame the dev too much for this. (IMO) It is right after this time where the story-telling part of a VN has to get better to hold the interest of supporters. The usual paths here are to keep introducing more females into the harem and/or add some 'corruption' kind of elements where things get 'kinkier' (this can be competition, dominance, lesbian, exhibitionism, etc.). Adding more females becomes repetitive quickly and kinkier will potentially (probably?) turn off a segment of the supporters depending upon the path chosen. There are a (very) few of these VN's that pull that off effectively and a large number where the beginning of the end starts here heading on the road to abandonment.
Since I am not a paying customer, my views on this matter not at all but I like this VN and I want it to continue. With that in mind I think the VN's that pulled off a somewhat effective transition are:
1.
Mid-Life Crisis (not exactly the same situation and ended up abandoned anyway...but could have been continued)
2.
My Employee's Family (not exactly the same situation and lost its way and needed rescue...but still ongoing)
3.
My Best Deal (still ongoing)
I think a combination of the "add females" and "corruption" will be needed and this dev clearly already knows how to keep things light and add humor into the mix. I wish the dev the best of luck.
