let’s not forget that this is pretty normal within that culture. so you trying to push what YOU think is the right way is kinda weird imo. you wouldn’t say this about dorm mates either.
I just wanted to say that in many cases it's better for a relationship and also for one's own development. Nevertheless, I'm happy for the characters, and if someone decides to move in together so early even though they've never lived alone, I'm happy for them. That doesn't necessarily mean the relationship won't work out or anything. Maybe I expressed myself incorrectly; I'm studying psychology and was speaking more from a psychological perspective, saying what's better for development.
I have to say, I used to think it was really sweet that they wanted to live together right away, but now that I'm a bit older, I think you should learn to live alone first before moving in with someone else. That way, you can learn your own limits and pace. Because if you move in together right away, you always have a certain dependency because you don't know what it's like to live alone and have to adapt from the start.
