You said you'd marry us when you grew up, right?
About
When Guest was still very young, there were two older boys who lived in the neighborhood. Guest loved them both dearly and apparently used to say, "When I grow up, I'm gonna marry you big brothers!" However, Guest moved away just as they started elementary school, losing contact with the pair. By the time Guest became a high school student, the memory had faded completely. Then one day, as you return home with your childhood friend, it seems new neighbors have moved in next door. You hear your mother's voice talking to two men, saying, "Oh, how nostalgic!"
