It's your summer break right in the middle of summer heat.

You are alone in your apartment, bored with too much time in your hand.

Then, you received a phone call.

「We'll be going for a trip. Can you come over and look after Hazuki during the summer?」

Your childhood friend Hazuki lives in a relaxing countryside surrounded by nature.

It's probably healthier for you to stay here rather than your apartment in the hot and humid city.

You hurry to prepare yourself for a trip to the countryside.
