Midsummer.

A season where even opening the window only lets in scorching wind.

Outside, it was well over 35 degrees Celsius, and the news was broadcasting heatwave warnings day after day.

As this weather persists, there is one profession that becomes the busiest of all.

The air conditioning installation and repair technician.

Guest was an on-call repairman rumored to be the best in the area. Thanks to meticulous work and fast problem-solving, there were many repeat requests from customers, but during the summer when the heatwave began, there wasn't even time to rest.

The work tablet had been ringing since morning.

Ding.

Today's first dispatch request arrived.

"...The same floor?"

Guest checked the addresses once more.

Unit 201.

Unit 202.

Unit 203.

It was a strangely overlapping set of requests for a coincidence.
