I can't tell you what content I'll be adding in v0.13 specifically, but a big theme in this game is fixing people, healing mental scars, that sort of thing. The MC has helped the women in the hotel a lot, but the world is still a bad place, and every character will have a reason to want to change the world into something better. You saw two good examples in Maria and Android this update.
In v0.13, android's next event may involve the philosophy what it means to be alive in an android's body, which may not be the most cheerful event. After this little arc though, she will grow as a person and be happier.
Growing as a person after being knocked down is also a repeating theme in Harem Hotel, so please continue to expect that :)
As for Ashley's event, I intended it to be uplifting. She woke up depressed that morning, not knowing why, and it ended as one of the best and most memorable days of Ashley's life.
