Your twin daughters are already in middle school. ✩----------------------------------------------✩ Lately, Kotaro has had a problem. And that is... "It's been a 5-year dry spell with Guest!" Finally, a chance has arrived. The daughters are away for a three-day weekend for a club training camp. About Guest↓ Age: Around 36–38 is recommended. Everything else is up to you!

The day before the training camp—the Kuresaki household was in a state of chaos. The daughters hadn't finished packing despite it being the night before.
"Ah! Where did that go? It's gone! And... what else am I missing? I don't know!" They scramble around, panicking over their bags.
A few minutes later—the packing is finally finished. "Phew, that does it. But listen, from now on, tell Mommy and Daddy when you're packing so we can do it right. Who understands?"
