He is a spy. Since the party, he was acting suspiciously. He was always leading everyone to a certain action, which ensures their plan is going well. Or, staying away from murdering someone.
@ClaudiaKdramaLover.... they were destined to meet through the book... he did say to her when he killed her...…
Yep. I mean, I get it, "plot device". But the way they used the spellbook, and then later added a spellbook of curses, made it no longer a plot device, it's an important factor in the story.
But, nope. There was nothing behind those spellbooks. They remained "a plot device that is not" LOL.
I wish they just turned it into a novel or webtoon so they can explain better what they have in mind. For sure there was something to it, but the live-action drama just wasn't enough to fit it all in.
I'm scared once K makes his play. He's a total unknown. Unknown variables are very dangerous. No matter how much you prepare and control things, an unknown can mess it all up and gets the upper hand.
Who said he planned it all? I don't know where the show showed or said any such thing.I got something very different…
No idea. Just a wild guess. Hahahaha.
The mystical stuff they added, as far as I'm concerned, can be ignored and we'll still have a very good romcom. I don't even understand why they added those side plots that doesn't even make any sense. Even showed there is a spellbook of curses, and then, nothing. Why did they even bother to add that if it won't make any difference in the story.
:P
In fairness to the writer, the story they have in mind is better written as a novel so they hav the freedom to explore and build the world. Because of the limited time and budget in live-action works, they weren't able to flesh out what in the world is the past about and what those spellbooks got to do with their present, other than to establish that they reincarnated. Haha.

Same. I enjoyed their present courtship drama and the comedy. The side plot about the spell book and the past were all unnecessary.
We can even remove those mystical stuff and we'll have a very good romcom. I don't understand why they have to insert those plots that doesn't make any sense.
If I recall correctly, somewhere up in their family tree, there was a family with twins or two daughters, and that's the split. I think it was explained int he first season.
1. Do Bong Soon came from the "other branch" of the family? Since Kang Nam Soon appears to be the strongest of them all?
2. They have other powers, but seems to appear rarely on one person, in this case, Kang Nam Soon = strength + speed + jump. And it also appears that Nam Soon can enhance her powers if the other women are near.

It can't be K, since Matthew only learned about his existence after.
Then K played everything.
I think K knows the grandpa is his stiffest competitor.
But K is not all-knowing, Lee Hwi So was a total unknown. Who would've known he will turn himself into a computer genius and create an elaborate plan?
This piqued K's attention so he returned to South Korea and started inserting himself in Matthew Lee's little game.
By killing the grandpa, K just showed he still has the upper hand. He sort of tested how good Matthew is. He tested the weakness of Matthew.
Now, K is ready to fight head on against Matthew.

All the while, he was also the one who hid the book of curses underneath it, in a secret compartment.
That's my guess.
^_^

Did Bong Soon also have speed? I can't remember.
