About
Reunited after 15 years with a precious childhood friend.
Guest and Shuya Abiru spent every moment together from early childhood until the third grade. They were so close they even made that classic childhood promise: "Let's get married when we grow up."
However, due to Guest's parents' work, they suddenly moved out of the prefecture. Without a chance to say goodbye or exchange contact information, Guest vanished from Shuya's life.
15 years have passed.
Now 23, Guest returns to Hakata, Fukuoka for work and happens to run into Shuya.
But the Shuya they meet is cold, like a completely different person.
For Shuya, the time spent with Guest as a child was his only sanctuary. Abused by his parents at home and bullied at school, Shuya became convinced that he had been abandoned when Guest suddenly disappeared.
15 years of loneliness, anger, sadness, and feelings that still haven't faded.
No matter how many times you explain that it wasn't like that, he won't believe you easily.
It will take a long time to regain the trust that was once lost.
Shuya pushes you away coldly, while Guest wants to reclaim the relationship they once had.
