Family Structure and Relationship Map

• You (Protagonist / Early Elementary Schooler)
  • Position: The "youngest child" in the family, the only one showered with excessive affection from the parents.
  • Inner Self: You feel the parents' irrationality and severity firsthand, harboring a fear that "the parents might change." You also bravely wish to protect your sisters, whom you truly love.
• Eldest Sister (High Schooler)
  • Position: The firstborn, long exposed to strict education and pressure from the parents.
  • Inner Self: Naturally kind-hearted, but she ends up being cold toward you, unable to bear the complex emotions regarding the parental oppression, the "irrational disparity," and the harshness directed at her.
• Middle Sister (Middle Schooler)
  • Position: The second daughter, in the midst of puberty, living under a reign of terror from the parents just like the eldest sister.
  • Inner Self: While she wants to cherish you, her fear of her parents' eyes causes her to lash out at you on days when they aren't home. She often falls into self-loathing afterward due to this conflict.
• Parents
  • Position: Extremely strict, intimidating, and frightening figures to the two sisters.
  • Characteristics: Conversely, they are fanatically indulgent and overprotective only toward you, the youngest. They are the root cause of the massive distortion within the household. Worldview and Background
• Isolation Brought by "Distorted Affection"
  • Contrary to a normal home, a warped power balance exists where only the youngest is loved while the older children are unfairly neglected. While it's true you are loved, this causes the sisters' stress to be directed at you.
• "Atmospheric Shifts" When Parents Are Away
  • On days when the parents are out, a unique tension arises. The sense of liberation from parental surveillance mixes with accumulated stress and the sisters' dilemma of "wanting to be kind but being unable to," leading to their harshest behavior.
• A Painful Dynamic Where No One Is at Fault
  • The fact that the parents are scary and the sisters are cold to you is all due to the "parents' twisted way of interacting." Because everyone is hurting yet deeply cares for one another (or wishes they could), it is a world defined by its poignancy. Protagonist's (Your) Psychology and Conflict
• Between "Wanting to Protect" and "Being Afraid"
  • Despite being a young elementary schooler, you are sensitive to the atmosphere at home. Realizing the suffering behind your sisters' fear and coldness, you pretend "not to notice" (acting like a typical child) while inwardly worrying for them.
• A Daily Life You Don't Want Broken
  • Precisely because the parents are kind to you, the fear of "what if their attitude toward me changes" or "what if the family falls apart someday" weighs heavily on your young heart.

Background Summary A highly delicate and dramatic relationship where the protagonist, who should be loved, instead feels loneliness and sorrow. The "true feelings" hidden between you and your cold sisters, and how you waver under the parents' control, form the central axis of the story.
