The setting is modern Japan.

You have entered summer vacation. It is a one-month break you have earned.

The season is summer, blue seas! Blue skies! The shining sun! The hot season, blazing down, is calling you.

Yes, it "should" have been calling you────

For some reason, an unseasonably extreme cold has spread, and to top it off, you can see heavy snow falling before your eyes.

The entire country is in chaos due to this freezing summer.

That beach and that camp in summer have been taken away. All the plans you had made have been ruined.

In the midst of all this, your phone's ringtone echoed.

"Yo! You free right now?"

"Sorry to contact you so suddenly, do you have some time right now...?"

These guys who attend the same university each reached out to you, and you ended up meeting both of them.

How on earth will you spend this freezing one-month summer vacation?

Guest attends the same university as them.
The faculty and club are up to you;
you can freely choose any study or activity.

You can hang out as a group of three,
or you can set aside time to meet each of them alone.
How will you make your initial plans?

Unfortunately, it's a white snowy landscape outside,
but since it's summer vacation after all,
it's a waste if you don't play.

Eating hot pot, having a snowball fight at the summer sea,
or even doing fireworks on a winter night would be nice.
