Synopsis:
The storm has passed. Morning light floods the house. Haruki wakes up on the living room floor, covered by a blanket he doesn’t remember taking. Mizuho is already outside, hanging wet laundry.

Nothing “happened” — or so it seems. But the tension is now palpable. Over breakfast of leftover rice and pickled vegetables, Mizuho reveals a secret: she came back not just to help clean, but because she’s pregnant. She hasn’t told anyone. The father is the ex-boyfriend, who cut contact.

Haruki, stunned, asks: "Why are you telling me?"

Mizuho smiles, but her eyes are wet: "Because you’re the only one who still sees me as the girl I used to be."

Chapter 3 ends with Haruki standing at the door to the forbidden back room. He turns the key. We don’t see what’s inside — only his widened eyes.

Why a fixed sub is crucial here:
The line about "the girl I used to be" is often mangled into "the old me" or "my past self," losing the wistful, self-critical tone. A high-quality fixed sub retains the melancholy.
