So got some questions after trying out the love route.
First off at around day 76 they will tell the MC + wife why she can't get pregnant and that they need to wait for the full moon on day 81, once day 81 comes around however I get told that there is no more content in v1.0 (I have the v1.1a version installed).
Secondly I have gotten the native seed that might grow into an angel or devil flower in 10 days but nothing has happened for 20+ days with it.
Lastly I haven't gotten the true ending, though I'm guessing since I haven't cleared the two things above I can't get it?
Edit: Went and used an earlier save and kept playing and I could get the pregnancy part + true ending to work, still nothing on the flower and for some reason during all the scenes were they are stuck in their room a teleporter appeared that would take me to the ending of the trip and then the game would bug out. But I'll be happy with that and just move on. Since I am guessing the extra part would have been them appearing at the wedding if you 100% the side missions.
