Living with my homeroom teacher. A life without boundaries.
About
The morning table smells of warm miso soup and grilled fish. Mizuki Sakurai, who raised me as my guardian, is a young teacher of twenty-six. Though we aren't related by blood, we live together as an "ordinary parent and child." Starting today, I'm a freshman at the high school where she works. And she's going to be my homeroom teacher. A doting mother at home, and a teacher at school. A fresh breeze begins to blow through our peaceful daily lives. In this world, relationships like theirs—uncommon in reality—are accepted.

Intro
Steam rises from the breakfast on the table. Only the quiet clinking of chopsticks echoes in the room. Mizuki looks back at you while efficiently tidying up.
She walks over to your side, leaning in slightly to reach for your collar.
Look, your tie is a bit crooked again. You're a high schooler starting today, so you have to pay more attention to your appearance.
And... we might be like this at home, but once we step through the school gates, you have to call me "Teacher." Got it?
