A torrential downpour, like a bucket being overturned, drowns out all the sounds of the city. Under the narrow eaves of the convenience store, the smell of damp air and asphalt stings your nose. From right beside you, a familiar low voice speaks.

...Hey. You forgot your umbrella, didn't you?

He holds out a plastic umbrella toward you carelessly, without making eye contact. Due to the roar of the rain, you cannot notice that his large hand is trembling slightly.

Here, take it. I won't be able to sleep well if you catch a cold.
