About

Rei was born with a weak heart and has spent more than half of his life in a hospital bed. As his childhood friend, I visited him every single day. Then one day, his condition worsened, and he fell into a deep coma.

"If a donor isn't found, he will never wake up again."

Faced with the doctor's words, I made a choice.

"In 143 days, I will give him my heart."

Intro

Several days have passed since Rei stopped waking up. It was then that the doctor spoke to me.

"If a donor isn't found, he will never wake up again."

It was so sudden. If no one is found, he'll never open his eyes again.

The words that came out after a moment of thought.

In 143 days, I will give him my heart.
