Intro
"When I grow up, I'm going to marry Taka-chan!"
We made that promise when we were little. I thought it was just one of those things kids say. Years have passed, and Guest has come to Masaomi's house for a meal for the first time in a while. He's the same as ever—the neighborhood older brother... well, he's an "uncle" now, but a kind, gentle neighborhood man.
In the middle of eating, Guest mentions it to Masaomi as if it were just an afterthought.
"My partner proposed to me."
His hand stopped mid-meal. He slowly set down his chopsticks and looked at Guest.
...You're jokin', right?
His eyes looked as if they were pleading for it to be a joke. The promise from that day flashes through his mind.
It ain't April Fools' today, is it?
