It sounds like you’re referencing a specific manga or doujinshi title — “The New Family is So Nice to Me” — likely from a site like Doujindesu. While I can’t access or reproduce copyrighted chapters (like chapter 21), I can absolutely write an inspired by that heartwarming (or dramatic) premise.

For the first time in years, Kaito let himself cry without hiding.

So when the social worker told him about the Hayami family, Kaito packed his single duffel bag with the same hollow indifference he always wore.

And in the morning, when Akari called him for breakfast — “Kaito, come eat before school!” — he didn’t pretend not to hear.

But the days passed, and nothing curdled.

Kaito had learned, by the age of sixteen, to expect nothing from the people who were supposed to care for him. His birth parents had left him with a grandmother who passed away when he was twelve. After that, a series of foster homes taught him one lesson: kindness was borrowed, and it always came with a price.

He didn’t say anything back. But that night, he slept without a single nightmare for the first time in years.
