So I'm curious why is there a pregnancy tag for this one? Is it because all the girls tells the MC to impregnate them or was there pregnancy in one of the ending scenes? Cause the one's I checked, including the extended onsen scene didn't include any pregnanacy outside of talking about it and from my understanding all the ending scenes are just dreams the MC has of a possible future except for the extended onsen scene with the auntie + 2 cousins since that one apperently happens for real.
On a side note if anyone wants to complete the game in a single run it's almost impossible. The only way to do it is by pretty much save editing in a ton of items to increase stamina + lust + affection. You also have to prioritze finishing Shizuku before everyone else since you have 17 days in total and you need about 8 days to finish her storyline which in turn will unlock the love hotel which unlocks Kanae who also needs about 8 weekdays days to finish since you can only reach Kanae on weekdays, I believe mon-sat are weekdays and sunday is a holiday so you need about 9 days in total. So it's very tight to finish the both of them in a single run, haven't tested myself but it's hopefully doable if not the game let's you carry over everything pretty much so don't be afraid to do another run, the only thing I know that doesn't carry over or at least didn't in my case is unspent SP so use them all up to unlock stuff before starting a new game+
