Tao and Kris were a couple. Were a couple. 

After their parents found out about them, they decided to split them apart by moving away. Tao went back to China and Kris stayed in Korea at the ever so famous, Seoul Academy of Arts. 

Sadly, Tao's parents found out about him contacting Kris through his electronics so they confiscated every electronic device that Tao could use to contact him. So Tao never gave Kris the proper 'good-bye'.

A couple years later and Tao had gotten enough money to go back to Korea and Kris.

But strangely enough, Kris doesn't seem like he remembers Tao. In fact, he doesn't even seem to acknowledge his existence.  

What will happen to the once so happy couple?
