I'm wondering....as the story progresses and were given the option to get an apartment,will we be given more than one apartment option based on income and circumstance?
Well, I think the variables in the files for Ian and Lena's living arrangements have been in the game since the early days, so it was probably always a plan to explore this idea some time. I recall Eva initially commented that she intended there to be a time skip, but it's kinda hard to imagine that would fit into the story with the amount of chapters left, even if we reach the max estimate of 20.
So far moving seems more of a necessity for Ian (if their's a decline in friendship with Perry) than Lena, their isn't much reason for Lena moving apart from getting additional privacy, unless she refused to having a friendship with either Stan or Louise and it creates conflict. Instead either Stan or Louise leaving made more sense after a decline in friendship, seeing as befriending one basically prevents really having a good relationship with the other and tbh I wouldn't be mad at the narrative if it resulted in Holly being the one moving in.
Well, Eva already introduced the rent hike. Seymour is buying property, so the suggestion might be that his purchases are driving up land values in the city, which is the cause of increased rent, even if indirectly.
So I could see Lena moving depending on her relationship to Seymour, as opposed to Stan and Louise, though they of course could still be secondary causes.
If Lena is on the Seymour route, would it not be a sensible development that Seymour offer her a place to live? Similar to how Ash can have the option to move in with Jess in GGGB depending on her status.
Alternatively if Lena is not on the Seymour route he could force rent up to a point where Lena can no longer realistically live as centrally as Stan's apartment seems to be, forcing her to have to consider moving away.
If this was the structure then Lena moving out would be a matter of when rather than if. Of course on the Stan route it's possible she could stay in the current apartment if Stan's willing to pay the rent, he does have full time employment. Ash could choose to stay in her childhood home in GGGB too.
When it comes to moving in with another Ian may have the option of either Cindy or Cherry and for Lena either Axel or maybe Seymour but that's based on romance?
Lena could potentially move in with Robert too, or Mike if he breaks up with his girlfriend. Eva will probably have to choose to make the main character's living arrangements either wildly dependent, or narrow it down to some specific options. The default could of course be Ian and Lena sharing with Holly, with dependent versions if one of them find other arrangements.
