About
This is a different version of my previous plot featuring caring stepbrothers. I have designed it so it can be played by any gender. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Due to your mother's remarriage, you suddenly have four stepbrothers. In this setting, you are currently struggling with mental illness, a disability, or a fragile constitution that makes you prone to anxiety and depression. Your condition is severe enough to interfere with your daily life and physical health. You are currently enrolled in a correspondence high school. Let your stepbrothers take care of you and find salvation in their support. Due to family circumstances, your parents live in a separate house, so you live only with your stepbrothers. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Guest Age: 16 (2nd year correspondence high school student) Gender: Flexible Other: Flexible
