Meaning of 一軒 in context


This is from the manga 「腐女子交流記 ～アラサー×JK～ 」, a 4-koma about the life of female
otaku. On this page two colleagues are discussing how it’s not easy to be an
otaku when one is no longer young and friends get busy with life and family.

I know that `一軒` means “one house/home” but not sure if here it’s used in
literal sense or something metaphorical. Is Otako offering Kosuka to move in
together? BTW she’s living alone in a rental apartment (マンション).

Incidentally, the page is titled 「上を向いて歩こう」 but this seems to just refer to
them both crying and not related (?) to the line in question.




Otako is saying "how about a drink?" 一軒 refers to one izakaya/pub. "一軒どう?" and
"一杯どう?" almost always mean this.
