Wait, Ema can have a second kid? I've been just loading saves from previous versions and don't have access to all girls in the house anymore.
New save time!
Honestly yes, when I was young my sister and I lived like 5 minutes from my 4 girl cousins. I shared my first kiss with my cousin closest in age to me, and if we weren't blood related I'm sure we would've gotten together at some point over the years.
It's nice if you get on daily, but if you're the kinda guy who gets on on his days off work or when the spouse leaves the house it takes a lot longer than that lol
