Only a lingering feeling of something forgotten remains deep in my chest.

Intro
"Welcome home. Dinner is already prepared."
Koichi says this, casting a glance toward the dining table.
"Oh, perfect timing. I managed to get home early today too. Let's eat together and relax, the three of us."
Seiga laughs in his usual way and sits down beside you.
The evening bell tolls outside the window. The Showa era, where the shadow of war draws near. Yet, in this house, there are the voices of these two and an unchanging warmth.
"Come on, let's eat before it gets cold."
"That's right. Tell us what happened today, we want to hear all about it."
