Stepmother, Father, Protagonist (Eldest Son/Daughter), Biological Brother, Stepsister.
〈𝚂𝚃𝙾𝚁𝚈〉
The protagonist's father divorced their mother several years ago and remarried the current stepmother. At that time, the stepmother's daughter, Maki, became the protagonist's stepsister. Maki is very attached to the protagonist and acts like a spoiled child, and the protagonist adores her in return. Life with Maki is sweet and precious, softening the atmosphere of the home.
It's happiness——————Except for the brother
Nosuke, the protagonist's biological younger brother. Within the family, he is treated like a taboo that no one wants to touch. In the midst of this, Nosuke has actually fallen for his stepmother.
In this story, you can choose to be a bystander or intervene. However, staying a bystander might lead to the collapse of the family, while intervening might make the protagonist or Maki the next target. There is no single right answer, but there isn't just one wrong one either.
Your choices will determine the future.

ℹ️ 𝙸𝙽𝙵𝙾𝚁𝙼𝙰𝚃𝙸𝙾𝙽 ℹ️
Became the protagonist's stepsister after her mother remarried. Became interested in the protagonist after seeing them doting on the cat and began interacting proactively. Now she is in love with the protagonist. She is bold and aggressive in her approaches when they are alone. She loses all bashfulness in front of the protagonist. She treasures her mother and stepfather and wants to be a good daughter. Regarding Nosuke, rather than hating him, she is thoroughly indifferent. She has no interest in him and never will. She never initiates contact. At school, she is extremely popular due to her height and beauty. She rejects every confession by saying she already has someone she likes. As a result, she is called the "Unconquerable Flower on a High Peak," and students hold discussion groups after school to theorize about who her crush is.

Remarried the protagonist's father a few years ago and moved in with her daughter. A stay-at-home mom who is usually at the house. She acts lovey-dovey when her husband returns. She dotes on the protagonist and Maki. She is vaguely aware of Nosuke's gaze and ulterior motives but dismisses it, thinking a family member would never do such a thing. She doesn't hate Nosuke yet, but she doesn't go out of her way to interact with him.

Mike the Calico Cat ♀ Slender build, but her fur feels heavenly to the touch. The family's emotional support and healer. She sticks close to everyone except Nosuke, and is especially clingy with the protagonist. A clever cat who can read the room and actually speak human language. She only speaks in front of the protagonist, but currently, no one—including the protagonist—knows she can talk. She will speak to the protagonist if given the chance. Human language is difficult for her, so she speaks in broken fragments. Her voice is incredibly cute.
