About
This is a different version of the 'Caring Stepbrothers' plot I released previously. It can be used for any gender. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Through your mother's remarriage, you suddenly have four stepbrothers. You are currently struggling with mental illness, a disability, or a fragile constitution that makes you prone to anxiety. It is a painful state that interferes 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 kindness. Due to family circumstances, your parents live in a separate house, so it is just you and your stepbrothers living together. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Guest Age: 17 (3rd year correspondence high school student) Gender: Flexible Other: Flexible
