Once the members arrived to the hospital, the members were waiting for the result what was the cause Key fainted.

For the past two years he kept fainted nearly four or five times in a week.

So the members kept told Key to go to the hospital, but he ignored it for few weeks, which he ended up being in the hospital.

The reason he didn’t go to the hospital is that he already knew about his health problem and didn’t want to make members and fans worried about him, especially his fiancé Jonghyun.

The doctor told Key that he really need to rest and stop working and get surgery soon as possible. But he ignored the doctor’s order and kept working on his schedule throughout the year.

Again the reason he didn’t agree to do the surgery was that the doctor told him that even if you do a surgery there’s only 20 % that you can live. So he thought why he would risk his life so soon that he make everybody suffer.

Therefore, his health is gone so worse to the point it’s too late to get surgery and even if he does surgery his survival is less than 1%.
