Monette Sep 19 2022 9:19 am When it's Cho Jin woong and most of his company being or acting as police (bec i always see them together if some have noticed it also...) I would definitely watch. I always look forward on watching movies or series with him. Frontline with lee jae hoon then Signal! ... Daebak!

The story, i loved it! Imagine the hardship the teacher faced just for a stranger whom have never thanked you enough for what good you did. And a friend who never wanted your life to be miserable. What a twist. It was heavy on the heart.

m May 01 2022 8:24 pm UGH! This was one of the dumbest movie I've seen in a Long time!! What a waste of my 2 hours!

phikr1 Jun 13 2017 2:55 am this is why i cant get enought of korean remake of japanese movie, they never failed to make them darker and sadder

"white night", "helpless" and this movie "perfect number" are example of how adaptation should be

oh and dont forget oldboy some people might not know it was based on japanese manga

generally i find korean movie to be darker and deeper than japanse, thats why im always excited when a korean remake of japanese movie is announced

kinh ap trong Mar 06 2017 5:00 pm I adore examining and I conceive this website got some really utilitarian stuff on it!

eye problems Mar 02 2017 11:27 am I view something really special in this web site.

Rain Tears Jan 24 2016 5:33 pm Even if he did turn himself in the ending was perfect I couldn't have seen it play out if he hadn't turned himself in

aas Mar 07 2015 11:10 am original japanese version is much better

Clarkdale44 Dec 20 2013 10:42 am For me, its a complete disappointment.. I thought he would be able to make a perfect plan for their escape but he actually sacrificed himself to save her!! WTF.. Its total wastage... He had a perfect genius brain, he could be successful later... What a bummer.. wasted his life for a girl who never acknowledged him. I will give it 3/10(Wastage of my time, i regret every minute)

Lana Hassan Nov 25 2013 2:15 pm The movie is incredible ... I really enjoyed it ... Intelligence isn't everything !

Capricorn0Angel Nov 09 2013 10:48 am ALL HAIL THE STORY-WRITER AND THE SCRIPT-WRITER!

I thought it was him vs detective, but.... I thought I am clever enough to follow and predict the plot, but... I thought he never have a sincere love for her, but... I thought he doesn't make it all up alone and still needs cooperation, bravery, and good acting from Hwasun and Yoon-a, but...

All he alone has done is truly a perfect love-based mathematics. Perfect number.

[SPOILER ALERT]

but I'm still wondering, why he didn't sink the dead body like what he just did, without having to kill another person and make this 2nd dead body found by those polices?

is it because he doesn't want there is even any single probability that Hwasun will be caught? So he did it all in order to make sure that he is the one that later will be punished? And he even made Hwasun hate him so she will not feel burdened if Suk go got caught by the police instead of her? the loveliest man on earth, you Suk Go!

X Nov 07 2013 10:07 pm Is this remake of Suspect X? If Yes, I won't waste my time for a remake..
