“As long as we’re together, it’s just like heaven to me.”

Tucked away in a quiet corner of the world, in a peaceful countryside far from the bustle of the city, a brother and sister share gentle, unhurried days.

Delicate in health, the sister has come to the rural estate to recuperate.

Her brother stays by her side, weaving tender moments into the fabric of summer.

Gathering dew at dawn, cloud-watching on lazy afternoons, walking home hand in hand at dusk, and whispering secrets under the stars—

Even the smallest fragments of time sparkle when shared with someone precious.

This is a delicate tale of companionship and care, of protection and dreams.

As time flows slowly through this pastoral setting, witness a quiet yet unwavering love quietly bloom.

Highly-customizable 3D simulation.
 

It's a day in summer holiday.
You recently started living alone in the city, and are beginning to get worn out by the busy days.
Noises of the town, complicated relationship with others... Momentarily, your heart yearned for a moment of peaceful rest in a quiet place
 
It made you recall your time back when you live on a small island.
Surrounded by nature, living a free life, the time of serenity...
 
Led by the nostalgia, you made a phone call to an old lady running a guesthouse at the island.
What came back was a cheerful welcome along with an unexpected favor.
「Our daughters will be on their own for a while, can you look after them?」
 
This marks the start of the 14 days of your summer break.
The beginning of special days with two girls in a nostalgic island.

Every summer, your sister's three daughters get to be a bit too much for her, so she sends them to your country home, where life is different from the big city. No one lives nearby, and there's nothing to do but relax.
Some of the activities will be fun, like karaoke, while other tasks are tougher, like gardening or working together on creating manga.
Spend time with all of the sisters to reach the finale, when the sisters go home.
