The Flower Left Behind For Us.

"If the world is against you it is also against me."

If you don't want to read a whole paragraph:
Kim Rok soo wakes up as Cale Henituse's older twin

Kim Rok Soo wakes up in a body with its memories. Ciel Henituse- The older twin of Cale Henituse who was killed before the novel starts. Currently the body is five year old which he couldn't care less. All Kim Rok Soo needs to do is survive his death and get away from the war that will happen. One problem. He already grown attached to Drew and Cale- his mother and twin, and now the mother dies leaving him and Cale. This makes Ciel realize the events in the novel WILL happen. Now he wants to stop it- with the help of his equally stubborn younger brother.

So basically Kim becomes Cale's twin then you know Drew dies, Deruth becomes a horrible father, Ciel gets a little clingy to Cale for a bit in fear of losing him, they meet the Thames, now they have to find out who they are own their own. The unlock abilities that help them be in snyc (?) with each other. While being Op ofc ;)

Also Cale still gets beaten to a pulp... Somehoe

Feel like I wrote the whole plot of the story down.
