‘One Day’ – Review
This review may contain spoilers

I was under the impression that the Thai only make awesome horror movies but this movie ‘One Day’ proved me wrong. Maybe I was just lucky to have stumbled across one of the good rom-coms of Thailand but this has made me more interested in Thai films!

One day is a bitter-sweet rom-com two co-workers who are from different worlds. Denchai is the IT nerd who lacks social skills and is practically a social pariah. No one remembers his name and he is simply a wallflower in the lives of everyone around him. While on the other hand, Nui is a social butterfly with a beautiful heart. She is always smiling and laughing and makes people feel special, even Denchai.

Denchai and Nui – two people from different worlds

Nui is the first person to remember Denchai’s name which immediately makes Denchai want to make her happy. He secretly starts doing small things for her like finding her favourite music or arranging her desk after work. He does it just to see her smile. He ends up even winning Nui’s Biggest Fan Award (You will have to watch the movie to find out more about this 😉 )

But, Nui is secretly dating her boss, Top, who is actually married and has a child but tells Nui that he is soon going to be divorced. Top, as the boss, declares at the official New Year party that the entire team will be going to Hokkaido, Japan for their official trip (which is supposed to be a secret romantic gesture as Nui really wished to go there and see the Snow Festival!)

Once the whole crew reaches there Denchai comes across a bell dubbed ‘Lover’s Bell’ which is believed to grant wishes (related to love obviously). So Denchai makes a wish, he wishes to have just one day with Nui. This is where the main story begins!

So the basic premise of this story is built around a medical condition called TGA (Transient Global Amnesia). Now I must admit that even when I first heard about this in the movie I thought the condition was totally made up. After the movie, I looked up the condition and it turned out to be a 100% real and the details were almost entirely correct! Here is the overview of the condition and if you are interested you can read about it in detail on Mayo Clinic:

Transient global amnesia is a sudden, temporary episode of memory loss that can’t be attributed to a more common neurological condition, such as epilepsy or stroke.


During an episode of transient global amnesia, your recall of recent events simply vanishes, so you can’t remember where you are or how you got there. In addition, you may not remember anything about what’s happening in the here and now. Consequently, you may keep repeating the same questions because you don’t remember the answers you’ve just been given. You may also draw a blank when asked to remember things that happened a day, a month or even a year ago.


With transient global amnesia, you do remember who you are, and recognize the people you know well. But that doesn’t make your memory loss less disturbing. Fortunately, transient global amnesia is rare, seemingly harmless and unlikely to happen again. Episodes are usually short-lived, and afterward your memory is fine.

So basically after the rest of her co-workers leave Nui continues to say in Hokkaido for an extended romantic get-away with her secret boyfriend – Top. Unfortunately, Top’s wife and son turn up in Hokkaido and their plans get sabotaged. Nui, depressed, wanders off on her on in the freezing weather and suffers a head trauma. The next day when Nui wakes up she suffers from temporary amnesia where she can’t remember the last 4 years of her life, not even how she got to Hokkaido or her boyfriend Top whom she had been dating for the past 3 years. She suffers from TGA but the twist is that this condition only lasts for a day and from the next day she will completely forget about the 24 (amnesia induced) hours but recall back everything else about her life except this one day. (These conditions are real!)

So where does Denchai come into all this? Well, seeing Nui distraught he decided to stay and secretly look after Nui and he is the one who indirectly rescued Nui. So when Nui wakes up with this make-belief-like condition, Denchai thinks that his wish is being granted and pretends to be Top and spends his wish-granted one day as Nui’s boyfriend.

The one day that they spent together was so sweet and lovely. He makes everything on Nui’s wish-list to come true. They have a dreamlike winter date. Watching them and the places made me want to pack my bags and immediately fly to Hokkaido for this festival. Nui also took some time get a grasp of her condition. At first, Nui was apprehensive and disappointed finding someone like Denchai to be her boyfriend but by the end of the day, she was in love with him too. But by nightfall, she finds out the truth about Denchai and how she is simply a mistress to Top.

The problem is that Nui will not remember him once the 24 hours are up so she decided to make a video message to remind herself to not forget about Denchai. This seems like the trick to get their happy ending but fate (read Denchai) had other things planned for them.

One would wonder why Denchai would do anything to stop Nui and him getting together and the answer lies in the movie. One of the scenes perfectly explains his reluctance in Nui finding about their day together. I wish I could tell you but I think you need it watch it yourself to completely enjoy it.

I absolutely loved Mew aka Nittha Jirayungyurn who plays the role of Nui. This is the first time I have seen her and I think she is gorgeous! I loved her acting. She brings life to Nui’s character (considering this is her big screen debut, she definitely has won hearts).

Chantavit Dhanasevi who plays the role of Denchai is definitely my favourite! He doesn’t look handsome or stunning but his acting made me fall for him hard. He is a complete natural and flawlessly assumes his on-screen role. What makes me want to appreciate him, even more, is that he is the co-writer of the movie! Talk about multi-talented.

The movie is well-paced and flows smoothly. I didn’t feel bored even once. There are lots of comic scenes as well and the romance is not particularly cheesy or over-the-top. I especially loved how they utilized flashbacks to maintain a sense of mystery, tension and curiosity from the viewer’s perspective.

Overall the movie was a delight to watch and I wouldn’t mind binging on it again sometime in the future.

Some scenes that I loved are,

Just watched it on TV and I’m so stress with ending. I wonder if they would end up together. In the very last part, it shows that Nui cries after watch the video and later she leave Top with a very emotional expression. I wonder if she’s start remembering Den but seems like it is quite impossible as what we know she will completely won’t remember that whole ‘one day’. Very confusing and too much stress on the ending. But overall, the movie was very very wonderful. Both actor amd actor and actress played their role very well. Excellent. Amazing… Read more »
