Renai Shinai Kekkon

Yume (31, single) is a beautiful and hard-working office lady who's been seriously working with Hayama-kun, her junior colleague at work, only to have others talk behind her back about their relationship. Frustrated by the gossip, she lets out her complaints while drinking at her brother's bar, only for a handsome stranger to overhear and suddenly propose marriage to her! She thought he was joking and brushes it off, but the next day, that man shows up for a work meeting at her office — Marriage out of the blue, even though they haven't even gone on a date yet!? Is a relationship like that even possible? A love story where a hardworking lady falls for a man who adores her to the point of obsession!
