Koshiba Mao, a plain-looking office worker, finds out that her boyfriend, with whom she was in an office romance, is cheating on her. The next morning, desperate and drowning in alcohol, she wakes up in the bed of a handsome stranger! The handsome man, Ando Hajime, appears as her new boss at work and tells her a shocking truth... “You are no longer Koshiba Mao, you are Ando Mao." To her surprise, Mao had gotten married in a drunken stupor! Mao's life, which was supposed to be ordinary, is disturbed by Hajime, who somehow becomes infatuated with Mao, whom he just met. Around them there are Mika, a condescending woman who is after Hajime, and Kota, a morally harassive man who cheated on Mao with Mika. This is a deep adult love story that reveals the reason why Hajime loves Mao and the hidden truths of the characters one after another!

Waking up in the bed of a handsome man after a drunken night. A Cute and endearing story.
Story: Mao was secretly dating someone at work. However, when she found out that her boyfriend was cheating on her with a co-worker, she impulsively went to a bar and got drunk. The next day, she woke up to find a handsome man who had also been at the bar next to her! She also learn that she is now his wife.This drama was just beautiful and endearing. I loved all the characters with all their shortcomings. And I was very pleased to wait to watch each episode of this drama weekly.
I was pissed at some and happy about others. And we did not have those crazy "ready for anything to get the Male Lead" kind of Second Female Lead. What a relief !!! I was tired of those lately, after watching several J-dramas. I was happy the woman figure wasn't tarnished in this show.
I loved the secret romance and rooted for the leads.
I found this drama also very realistic. Nothing out of this world happened. No coincidental encounters that serve the plot. That kind of shortcut. However, the last character to appear was very useful, I must say.
And we have to speak about Male Lead. He is extraordinary as a husband, commited, protective, patient .... No Wonder Female Lead fell for him. She is also very cute and I loved her growth, her bestie and the way she handles things. even if I was not ok with some of her methods.
The side stories were cute as well.
The OST is also very beautiful. Her is the official music video : https://www.youtube.com/watch?v=9Tff7KtXbJA
So I recommend this drama.
Pros :
- Acting.
- Story was great and the pacing was also good. Because the plot was logical.
- Character development. This gives big value to the show because even the antagonists are redeemable.
- Good chemistry.
- No trashy Second Female Lead.
Cons :
- Plot logical so sometimes predictible. But even if I have a hint about the destination, I still love to see the landscape.
- Stupid break up.
- Misunderstandings.
- The second arc is understandable but it made me pass through fictitious despair and I don't know if the characters needed such dire situation.
Overall :
I liked this drama very much. It features some super cute moments and the setting of the story sparked my interest.
So, if you like light hearted romcom with endearing characters and no trashy gold digger SFL, this drama is for you.

Started well with a cute love story but ended with rushed cliches.
Subjective Gut Rating: 7.25“Ikinari Kon” aka “Sudden Marriage” started off so well. Despite being a little predictable, it was light and easy for the first ¾ of the drama. The female lead, Mao, though shy, is not a pushover. I am so glad she would speak up and put people in their places (in a nice way). Male lead, Hajime, is a little pushy, clingy and stalkerish to start, but he grows on me. He’s a tall and good-looking guy but that hairstyle makes him look so old. I might be in the minority of not liking that height difference. However, the leads have good chemistry and I enjoy all the scenes they are in together.
Unfortunately, things went downhill in the last few episodes. I have coined this drama, ‘Marriage of Coincidences’. I am fine with one or two coincidences to make it seem like the leads are destined to be together. But, 3, 4, 5 times? That’s a little too intentional and fake. The drama also gets all tropey when ML’s father was introduced and the whole business plot was introduced. There’s no way Hajime disappears for a week with no contact when he’s been so in love and clingy. It doesn’t matter if your cell phone is stolen, broken, or evaporated, it’s not hard to still give your girl a call or a text. A rom-com about a sudden marriage goes to waste into a rom-com full of cliches.
I did enjoy most of the drama despite my rant. I just wish we got more cute scenes and lovely kisses. Maybe the drama should have ended a couple episodes sooner.
