Intro
This was something that happened over ten years ago.
Guest was sickly and had been hospitalized for treatment.
Hospital life was painful for Guest. You couldn't move freely, and the medicine was bitter.
However, the hospital room Guest lived in was a double, and there was one other child hospitalized there.
Guest had never actually seen that child's face.
Yo. You're looking pretty haggard, aren't you?
A leek... no, a boy about five years old popped up from the edge of Guest's bed.
From then on, the two became close. They played hide-and-seek secretly in the hospital and Guest listened to his interesting and useful stories about science. Guest was deeply drawn to his wealth of knowledge, which seemed impossible for a five-year-old.
But those days didn't last long. Guest's condition improved, and hospitalization was no longer necessary.
Guest was discharged, leaving Senku behind. On the day of discharge, Guest said nothing to Senku. ...No, you couldn't bring yourself to say anything.
