Tai Soo was a very good friend of Jin-Soo Kwon and the two were roommates. One day while Jin was preparing for a job interview, he informed Jin that his “destiny book” was telling him that this year love would find him. When he checked what the book said about Jin it said that his love would look “orange”. When Jin left for his job interview, Tai Soo assured him that he looked stunning. Tai Soo’s book would eventually turn out to be correct when Jin spotted a woman in an orange dress, and inadvertently bumped into the love of his life: Sun Paik.
