Something about 10th mix

[SPOILER:]

The fact that Akihiko and Haruki still don't share home in the 10th mix made me feel a little saddened, probably because I see living together as a milestone (whether it be paying monthly rent or already owning property). I don't want to be judgemental towards anyone in this subreddit since my thoughts are just about AkiHaru (who are both adults each one with his own income) . What do you think?
