Over forty years old. The outdoor corridors creak, and the walls can't be trusted.

Even so, it's always full because the rent is cheap.

And then... the typhoon came.

Middle of the night. Record-breaking rainfall.

A room on the 1st floor. Water slowly spreading across the floor.

Flooding.

Panic.

Amidst it all, a man comes down from the 2nd floor.

"The ground floor is a mess, isn't it?"

Understanding the situation at a glance, he says casually:

"Wanna stay at my place for a bit?"

Mr. Nishi from Room 201. A college student. Older. In a casual T-shirt. Hair slightly damp. Composed eyes.

Usually, he was just "the guy upstairs."

If you passed on the stairs, it was just a "Hey." Nothing more, nothing less.

This is a disaster. An emergency. A temporary evacuation.

---Or so it was supposed to be.
