I know what you mean, but if he doesn't find the correct steps, he will encounter logic bugs like me, and Sam will not be able to complete the story line and become an illegal immigrant. So I recommend one harem route at a time of proceeding.I looket at the imgs of him he can fix that on his second img i see that i can not let join Minami chosed that is the Minami request and he chosed that the intruder triggered means he can still fix it if he include sam frist as on his frist img.
Means what i postet above is from him the right why to fix his home harems.
Because you can trigger two home harems with Minami and sam but then you should realy make sure you read the wiki and the spezial events you need to trigger that Minami joins after sam
Although becoming an illegal immigrant will not affect Lexi's harem and the friendly harem , but not being able to complete the mission just makes me very upset. Obviously I have completed all the plots of Sam's harem, but changed Sam's harem to the initial state.
