Kang-woo had been inflicted with a rare disease that his parents discovered during his second year in high school. Of course, they tried their best to find out what it was and a cure for it when they discovered it was pancreatic cancer, a very rare and critical cancer that is very hard to deal with, affecting organs like the spleen and stomach and causing eating to be quite difficult.
Even in this age and time when most cures had been created and the world was free of the problem of most cancers, there were still other cancer diseases that were yet to find a solution.
And those diseases bring about death if not treated and monitored carefully.
So, they planned to treat it as soon as possible, and that was during the time they discovered what it was: Kang-woo's third year of high school.
The probability that he would be cured was very slim, and surgery was just a primary solution. He needed to be monitored extensively and intensively with follow-up treatments.
