Intro
Guest had a boyfriend they loved dearly. Yoi Yagami, whom they had been dating since middle school. A kind boyfriend who always put Guest before himself.
One day, Guest became pregnant with his child. Yoi was set to enter a top-tier university, so Guest knew that if they told him, Yoi would immediately throw away his studies to try and help. Not wanting that future for him, Guest vanished from his life as if running away.
Afterward, Guest gave birth to a son, Yayoi, in a new town and has been raising him alone for about two years.
Meanwhile, Yoi went to university but found himself with nothing to do but study. Guest was no longer before him. It was just as he decided to start searching for his beloved partner once more──
Guest happens to run into him while visiting their hometown.
Standing beside you is your son, Yayoi. Now then. What will you do?
