Bro, I get that you a little bit excited with the girlfriend boyfriend thing, but you guys known each other for 7 days. Chillll. Also, If they do live together, I feel like it would be more logical to sleep in separate rooms with the alarm clock.
Honestly im all for it, some people marry within a month, or even immediately!!
Infact, one of those people is my older brother who literally went to the house of the girl she likes, talked to her father and said "I come from [insert family], and I wish to marry your daughter." And in a few weeks of preparation, they did get married!
Honestly i don't know how my older brother managed to do that lol but they're happily married
