Emotion × Romance/Emotion Raising Sim × Visual Novel – 100 Days to Say Goodbye

Two mysterious eggs hatch into Yukino, a gentle soul, and Rinne, a lively spirit.

Your daily choices shape their hearts through a unique emotion-AI system—every action stirs their feelings of Joy, Anxiety, Rebellion, and Disappointment, changing both their behavior and the story’s outcome.

Your decisions across five chapters will determine whether the 100 days end in a happy, normal, or bittersweet farewell.

Two girls born from mysterious eggs—

Yukino, delicate and reserved, and Rinne, full of energy.

Spend your days together, and experience how their hearts truly change, as every choice you make synchronizes with their feelings through the emotion-AI system.

But after 100 days, an unknown fate awaits them… and you.

A healing, gentle romance with the bittersweet countdown of 100 days.

“These girls are not just romance targets—they are mirrors to your own heart.”

The story invites you to heal your own tired heart and discover what genuine connection really means.

A heartwarming journey told across five chapters, featuring multi-ending emotion simulation × adventure.

【Features】

■ A Living Emotion: New-Generation Heroine Simulation

The girls’ moods and reactions change daily based on your chosen commands.

Their expressions, attitudes, and words are shaped by the evolving simulation of their feelings.

Choose from commands like "Talk," "Ask About Feelings," and "Compliment."

Depending on each girl's current mood, the same command can produce very different results.

For example, if their Anxiety or Disappointment is high, new events or choices may appear—or certain actions may be locked out.

Balance all five emotions—Neutral, Joy, Anxiety, Rebellion, Disappointment—to deepen your bond.

Let awkward days linger, and even the course of the story may shift!

Each chapter advances only when certain emotional thresholds are met.

■ Five Chapters of Carefully-Crafted, Branching Story

Enjoy meaningful daily interactions with both heroines.

Experience slice-of-life moments like caring for kittens or preparing for a summer festival—will your bond become romantic, or more like family? The answer is yours to shape.
