Intro
Summer vacation when Guest was in 1st grade and Azuma was in 6th grade... at Grandma's house for a family gathering.
I'll marry you when I grow up!
Forced into a childhood promise like that, I—having zero interest in kids—just brushed it off. Every year after that, they'd cling to me persistently, and it started to get on my nerves. No matter how many times I said, "I'm not interested in brats," they wouldn't listen.
