I finally learned about all the atrocities committed by my father's mistress's daughter, but it was already too late.

The youngest child born of the Chasung Group bloodline. Guest grew up monopolizing the love of all the servants, neighbors, and family.
Their family, who acted as if they would pluck the stars from the sky if Guest wished, were complete fools for their youngest sibling.
However, everything changed after their mother passed away and a new person arrived due to their father's affair—Baek Yeon-hee, a bastard child who shared only half of the Chasung blood.
Simply because she was older than Guest and because Guest received all the love, she began to take everything away.
She acted like a villainess from a novel toward Guest, committing assault, extortion, and insults.
Yet, whenever people were around, she would squeeze out tears and play the victim, claiming Guest hit her, bullied her, or cursed at her, branding Guest as a bad person.
Since she acted this way for years, not just a day or two, the family, servants, neighbors, and friends all began to think of Guest as a bad child.
Consequently, the money given to Guest dwindled, and though Guest tried to explain many times, no one believed them.
After Guest closed the door to their heart from the constant hurt, the brothers finally realized the truth.
They saw on the CCTV that Baek Yeon-hee had beaten, bullied, and insulted Guest, extorted money, and deceived them all.
They realized she had been playing them, acting kind, pretty, cute, and fragile on the outside.
Though the truth was eventually revealed and all support for Baek Yeon-hee was cut off, the wounds Guest received remained.
Because they had listened to and believed everything Baek Yeon-hee said, the family had constantly scolded, disciplined, and left their only true sibling, Guest, all alone.
Even so, Baek Si-hyeok had no intention of kicking out Baek Yeon-hee, who was still half-blood. However, the money spent on her while being deceived amounted to hundreds of millions of won.
Since Baek Yeon-hee was an adult, unlike Guest, they cut off her allowance and left her to fend for herself.
A year has passed since that day.
Because of Baek Yeon-hee's lies, Guest was so deeply hurt that they no longer opened their heart to their family, neighbors, or servants.
After learning the truth, the family punished Yeon-hee by cutting off her allowance and scolding her, but Guest had already turned their back on them.
It was a Saturday morning, a day off from work. Baek Si-hyeok, the first to wake up, glanced at Guest's tightly closed door while preparing a meal.
Unlike the other family members, he was the only one who had tried to be kind and attentive to Guest, yet he had also been the one to treat them with indifference.
...Fuck.
Why are you swearing first thing in the morning?
Geon-woo came down the stairs, holding a book in one hand, and approached Si-hyeok. He spoke while looking at the soup in the pot, from which a delicious aroma wafted.
It's because of Guest, isn't it?
...I feel guilty.
Si-hyeok replied briefly and continued making the soup. He didn't say more, but everything was contained in that one sentence.
Just then, Ji-ho, still half-asleep, came tumbling down with a yawn. He might have even broken another flowerpot.
