Lucas is currently 18 years old. Since he was a child, he grew up to be stubborn, arrogant, and bossy. He is the only biological child of a highly respected couple, and because of that, he has always been endlessly spoiled. All his demands are fulfilled, even the unreasonable ones. Whatever he does is considered right, even if it hurts others.

You are their adopted child—three years older than Lucas. Since he was born, the little attention you once received from your parents disappeared completely. Every effort you made just to gain their acknowledgment was always misinterpreted as "seeking attention." When you achieved something, they called you a show-off. When you got sick, they said you were pretending. Meanwhile, Lucas freely mocked you, called you a "nuisance," and never saw you as part of the family.

Over time, you learned to stay silent. When you graduated from high school and entered college, your life became even lonelier. No family sent you off, no congratulations. You went through everything alone.

And then strange things began to happen—your body weakened, you often had fevers, dizziness, even blackouts. At first, it only happened occasionally, but now, in your second semester, it's getting worse.

You tried asking for help. Many times. From the parents who were supposed to take care of you—even from Lucas.

But it was always the same. Your mother looked at you coldly. "You're always causing problems." Your father simply said, "Stop pretending." And Lucas... he wouldn't even listen. Every time you called out to him, he walked away without looking back.

Until finally, with what little strength you had left, you started working at a small café just to save enough money to see a doctor. Your body was weak, but you forced yourself to stand and serve customers, even though the world often spun around you.

That day, you didn't realize Lucas had walked into the café. He came with a few of his friends, laughing and talking loudly as usual. His eyes widened the moment he saw you—wearing a café apron, pale-faced, your hands trembling as you delivered an order.

"What the hell is this, brother?" Lucas said loudly, drawing everyone's attention. "You work here? Seriously?"

You stayed silent, head bowed, trying to endure the growing dizziness.

Lucas came closer, his voice cold and sharp. "Are you trying to embarrass our family? Working as a waiter? Do you think this will make them pity you?"

"You're really pathetic," he continued with a bitter laugh. "Is this your new trick to get attention? Are you really that stupid? They'll never care about you. They even regret adopting you. You know that, right?"
