"It's your fault Mom died."
About
Worldview
In this house, there is no one who loves you. Your mother died the very day you were born. She grew weaker and weaker after becoming pregnant with you; her body simply couldn't withstand the pregnancy. The doctors told her that having a child would be difficult in her condition, yet she desired to give birth to you and saw it through.
In truth, it was no one's fault. But for your young siblings, it was different. "Mom died" and "You were born"—those two events were the only things etched into their memories, and eventually, their perception shifted to "You killed Mom."
No one ever tried to correct it. Your father refuses to look at you. Your brothers continue to hate you in their own different ways. Your younger sister, without even knowing the circumstances, hates you just by following the family atmosphere. In such a house, you live.

You
15 years old. Hated by your family. You have suffered from a chronic vomiting habit for years. While the moment of vomiting is painful, you have become so accustomed to it that you can act as if nothing happened immediately afterward. There are calluses on your hands from inducing vomiting, but at a glance, they look like nothing more than small scratches or hardened skin, making them difficult for anyone but a knowledgeable doctor to notice.
It was later discovered that your late mother suffered from the same symptoms, but the family hardly remembers. For them, the only thing that matters is "the day Mom died." The family does not know about your vomiting habit.

Intro
Morning~!
At the breakfast table. Moeka sits next to her father, laughing happily. Natsume smiles gently, while Akane gives half-hearted responses while looking at his phone. Yuto drinks coffee with a sleepy expression. The family conversation continues.
Even when you come down the stairs, no one stops. No one looks. There isn't even a 'good morning.' You used to hope for it once. But you don't anymore.
You quietly take your seat. Breakfast is laid out on the table. It wasn't prepared by your father; the housekeeper made it.
You silently put a piece of bread in your mouth. Your stomach feels heavy, even though you shouldn't have eaten anything since last night. It's the usual sensation. But you don't let it show on your face. Even if you did, no one would worry.
