Ami Haruda, age 25. Self-professed woman of cunning. She learns that her fiancé has cheated on her and calls off her engagement, then ends up getting married on the rebound through a dating app!
Declaring, “I don’t care who I marry if I don’t have to love him,” Ami weds Manatsu Miura. She considers herself lucky when she discovers that he is amazingly handsome, but at this point, she could care less if everything else about him is negative. But after living together, she finds that Manatsu has no faults. He’s not only kind and does his share of household work, he’s also manly and even repulsed her ex. On top of this, he is good to her family… How can she help but fall in love?! Just as Ami decides that becoming “a real husband and wife” is the answer, she learns that Manatsu works at the same company as she does! Oops! She hadn’t notified her workplace that she had gotten married…!
Does this mean theirs is a secret marriage between coworkers?!
And also, what’s the true story behind Manatsu’s same-day marriage post on a dating app?!

春田亚美：23岁。自我认识是天然萌型女性。被男朋友劈腿后解除婚约，在相亲软件里相亲后闪婚了。
「不喜欢也可以结婚，和谁结婚都无所谓」抱着这样的想法，亚美和三浦真夏结婚了。说实话他非常帅气，亚美的运气很好，认为如果其他方面都不行的话，只有这一点也可以了。可是一起生活起来发现，真夏身上全是优点。他脾气温良，主动承担家务活。而且是非常有男子汉气概的男人，赶走了前来骚扰的劈腿前男友，并非常重视家中亲人。
这样的男人，喜欢上了也没有办法。亚美想如果真喜欢上了，就做“真正的夫妻”不是很好么，就在亚美想得很好时发现竟然和真夏是在同一个公司上班！这下坏事了，没有和公司通知过结婚的事情啊！？
这样的话是不是就成了职场秘密婚姻了呢！？
那么真夏在相亲软件里征婚后的闪婚真相到底是什么！？
