Didn't We Say We'd Live Together If We're Alone at Thirty?30 made Hitori Dattara Issho ni Kurasou tte Itta yo ne ?; 30まで独りだったら一緒に暮らそうって言ったよね？

I thought it was just a drunken promise: “If we're both still single by 30, let's live together.”\n\nJust before her 30th birthday and in the dead of night, a suspicious figure appeared at Tsukiko's door—it was Sora, the one whom she'd made that promise with.\n\nNot exactly glamorous, but surprisingly fun—a thirty-something cohabitation adventure♪\n\nーFrom Takecomic.jp
