Evaluation

Sickly Days and Summer Traces released on June 20, 2025. Since launch, developer Sister Position has shipped three major content updates: Append 2 on November 7, 2025, Append 3+4 on March 27, 2026, and Append 5 on June 27, 2026. This establishes a clear and consistent post-launch pattern of substantial additions arriving roughly every 3–4 months. The most recent update shipped on June 27, 2026 — less than 2 months before today — placing the game well within the expected window for another update. The developer has not indicated that content development has concluded, and the numbering convention ("Append 5") suggests additional entries in this series may follow. The game continues to receive new content.

■ Story

“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.

■ Gameplay

  • Step into the brother’s shoes and experience life together with your sister;

  • Explore different scenes and interact with the world around you;

  • Talk with her, spend time together, care for her, and gradually deepen your bond;

  • Walk hand in hand toward a peaceful, happy tomorrow.
