1: No (The main girls are all friends now and have scenes together. It would be too much work having to make the scenes diferent based on whether they are together or not)
2: No (We will probably see the future but I dont think 10 years are needed. In 3 years the MC graduates and then in 3 more years he probably already has his life sorted with the main girl and maybe some kids idk...)
3: No (Will probably get a new minigame but based on the Q/A, DPC already made a guitar hero style minigame and it didn't work...)
4: No (With more than a year between episodes and the bigger branching I don't think its possible. Any PC upgrade will not speed up the production of the writing chaos that is the branching.)
5: No (Impossible to predict but I don't see the need for her having siblings)
6: Yes (It will be revealed in the future it could very well be next episode. Maybe the title for the next episode could be something like "Revelations" where many secrets are revealed (Bella's room, Magnar's information, Sage's Mom, etc...))
7: No (The route exclusive to Lily will probably be the romantic. If we choose the rolling we will probably be in the "Others" path or another side girl path in season 4)
8: No (She will find him atractive enough to be a male model but will not do any thing more than a little teasing perhaps (The model in the preview tho...))
9: Yes (The brawler minigame that Magnar is coding probably has malware and infected the DIKs computer

)
10: Yes (The location she is in look expensive and we never seen it. If Iris designs expensive clothes then it makes sense this being a location where she shoots her models)
