The dev just posted this on discord:
"My plan going forward is as follows:
The name I've chosen for the game will be 'Unexpected Family' (Sudden Family was a close 2nd)
I will be doing a time jump, but first I need to set things up for it.
So I first need to get Jasmin corrupted and then also have Katie move in with the MC, then I will be able to make a jump in time and age up the girls, and then relations can begin with them.
(The time skip will also allow me to make some alterations to the MC's home that I need to make, ones that logically cannot be done in a day)
The time skip will likely be about 3-4 years.
(^That's the time skip and not how long you have to wait for the time skip update)"
The reason why he is changing the name again is because there is already a game called love & corruption.
