From 12.59 a.m., Fridays, 13 November – 25 December 2020
After her boyfriend cheats on her, 23-year-old Haruta Ami breaks off their engagement and registers herself on a matchmaking app out of desperation. She finds Miura Manatsu’s post “Looking for a woman who will marry me on the same day” through the app and they get married immediately without knowing each other’s face, personality and background. Ami had been drawn to the words he posted and was desperate enough to choose marriage thinking that she does not need love as long as she can get married. The couple start to go through the motions of newly wed life but Ami finds herself gradually attracted to Manatsu’s kindness and manliness. They rapidly grow closer as they feel their way around. However, the two of them later find out that they work for the same company! As they are not able to disclose their sudden marriage to the people around them, it becomes a secret office romance. However, their colleagues and even Ami’s masseur begin to detect changes in the two of them. Furthermore, Manatsu has a secret for the same day marriage. The sham life of this newly married couple vacillates wildly but is tinged with sweetness.
