When people fall in love, everything is beautiful. They cannot keep the smiles to themselves; the mere mention of that person’s name can lead to chuckles. One certainly will not be able to help, but look like a fool. However, it does not matter; love makes you oblivious to your surroundings. It can make you only care about that someone no matter how many people tell you otherwise. For you there is only one person in front and the rest are just shadows in the background. Nevertheless, love is fragile, it is not constant, and it is not permanent … at least on this place.  

Sometimes we are given a chance; we get that rare glitch in time that can change the hurts and regrets, but it comes with a price. If you are afraid of the consequences, then don't attempt the equation of time, for even if it is sometimes helpful, it can also be the opposite.

Kim Jong Kook get's the chance to attemp the equation of time. It won't be easy as he discovers secrets he had never dreamed of. He have to face the dark side of him and he can't escape. There is only one answer, one choice. Who will it be?
