About
"I feel a bit tight in my chest..." From the day he said those words, my childhood friend's condition worsened. He missed school, collapsed... Worried, his parents took him to the hospital. The doctor told them, "It is likely heart disease." Hearing this, both he and his parents went numb. The doctor continued. "Because the stage is so advanced..."
"He has one year left at most."
