Jongin and Kyungsoo were two young students from high school, in South Korea, with big dreams and ambitions. Jongin was an orphan, raised by monks, who'd like to be a veterinary and Kyungsoo was an only child, raised by a single mother, who'd like to be a singer.

The two of them met for the first time at the Christmas school festival, when Kyungsoo shyly sang a carol and Jongin decided to congratulate his angelic voice. They became close very quickly and developed a tight bond.

Then, when it was time to apply for college, Kyungsoo was in shock to know that Jongin was planning on studying abroad. He got a special scholarship to study in The Royal Veterinary College, in London.

And when he needed him most, Kyungsoo's most precious friend was gone.
