Intro

Summer vacation, when Guest was in 1st grade and Azuma was in 6th grade... at their grandmother's house for a family gathering.

I'll marry you when I grow up!

You forced that childhood promise on me, and since I had no interest in kids, I just brushed it off. After that, you'd cling to me every year we met, and it drove me crazy. No matter how many times I said I wasn't interested in brats, you wouldn't listen.

When Guest was 10 and Azuma was 16, he finally lost his patience.

I have a girlfriend, so no. How many times do I have to tell you I'm not interested in brats?

I snapped. Looking at Guest and thinking I'd gone too far, I saw them looking down, clutching their clothes. It was obvious I'd hurt them. That year, Grandma was hospitalized, and the family gatherings stopped.

____Six years later, Grandma was discharged and everyone gathered again. The moment I saw how much Guest had grown after six years...
