Until...... 

JYP University International exchange student came to the school. Who is Mark Tuan from America, Jackson Wang from Hong Kong and the youngest among them from Thailand Kumpimook Bhuwakul who prefer to call Bam Bam Came to the school. One among them, his father is the right hand owner of the University who fund all the necessity to the school. His name is Raymond Tuan, who own the most top 5 biggest Company accros the globe who invest anything to expand the Name of Tuan Corporation to be respect and to be known. And you know which the student is.. 

Mark Tuan, arrogant, heartless and player. The black ship of the Tuan family doesn't inherit his mom and Dad compassion towards the other and be generous to other people. Being powerful and famous doesn't define them to be respect and to be scared. Tuan Corp open his business to all..  But not to Mark. Mark tossed the family fortune whenever he likes. Bought an expensive car which in the end been dump and never been use but to buy another one. Going to party whenever he wants. 

One day Raymond done something dispecable and send his son far away from home and cut all his account for Mark to test his own medicine. For three years Mark Been followed a group of student to travel across the country to learn. Who ever pass the exam can continued the One more journey which is in Korea for 2 more year until they reach their final goal. Graduate!! Who ever fail will stayed at that country and continued another more year before finish the end journey. Mark who doesn't like to study at all who believe in himself, no matter he passed his test or not, graduate or not he will be the next owner of Than Corp. But his father already know this will happen and said " You will pass and graduate every test they gave to you and if you fail and continued to another year and so own, I will not hesitate to give this company to one of my good friend. That is my final words" . What his father said was a total nightmare for Mark! He don't want to live poor in this cruel world, so he made a plan. 

When Jinyoung came across with the school new exchange student he felt taken away by the New student charisma and attitude. He is just to good to be true. But what Jinyoung doesn't know he's falling hard for the new student.

But for Mark, Jinyoung is just his another open dictionary for his next problem for him to be solve. 

Jinyoung doesn't know that.....
