Liked the story but not the acting or directing. It has so much potential though. It just had too much going on and unrealistic reasoning in too many places. It needs a lot of work to be redone properly.

Hong-bin's wardrobe was so ugly!!! The actor should have been respected more and offered a first class stylist. Not this garbage bin style he was left with.

Shin Se-Kyung was the wrong leading lady for this one. Her overacting was horrible to watch and she didn't come off as cute, at all, in my eyes. She successfully came off as sweet and loving as well as sincere but she has zero romance or sex appeal. She really didn't sell me on her love for her leading man. Lee Dong-Wook deserved a better partner for this story because it required so many layers and she was just one dimensional, this time around. She cost this drama a lot of point losses. Some of the losses did come from the directing and writing too, though. I loved her in The Bride of Habaek, just not in this drama, but then again, the writers and directors were crap too.

The music? Like some creepy psycho movie, there were a few really childish songs playing. I know it's likely because this is a fantasy movie, but it played more like a psycho killer doll was going to show up and slash everyone to pieces.

Now, let's go over the medical issues. The character Se-dong keeps fainting and gets dizzy at ridiculous moments. I laughed out loud when the doctor told her she needed counselling for her fainting spells. Heck, I cheered! The only real world explanation for her fainting spells, based on this story would be PTSD but even that doesn't fit the bill. It was just oddly written into the story and acted out poorly.

The ex, too, has a weird medical issue. She's dying because of a bone fragment near a blood vessel, that IF operated on, COULD POTENTIALLY, kill her. She uses her maternal instincts as a reason for not opting for surgery but a real mom would go get that surgery, especially if she already gave up the kid and let him think she was dead. Knowing she could die anyway and with all that pain, surgery is the only option for her. I sure would not want to live without my kid. That was several wasted episodes in themselves.

If it ever gets a remake, I'll take a chance on it and watch it again, but this version, I was happy to be done with.

What's this story about?

Some really mean guy with a bad personality meets a girl who isn't intimidated by him.
She's an orphan
Turns out he has superpowers.
He has a kid with his dead ex girlfriend.
He, of course, falls for the sweet unabashed girl before finding out his ex isn't dead after all.
He hates his father.
His father's old mistress is his housemaid.
The exes parents are old and simple and her mom has dementia.
The medical issues appear and are confusing
The secretary steals the show IMO
The kid's OK, but really not a part of this story much.

The last 60 seconds of the movie are their only great moment in it.

There are too many issues with this one. It sure didn't need 18 episodes. I forced myself to finish watching the whole thing because I am always hopeful things will turn out well, but this one never did.
