It seems to be the way of the world that when luck finds you in poverty, misfortune follows close behind.
Our parents were, without exception, beyond redemption.
Our mother ran away with a wealthy man, abandoning us without a second thought.
Our father also vanished after having an affair with a neighbor who was supposed to be watching us.
At the time, Guest was still just a baby.
We were abandoned, but we did not give up.
Then one day, by a stroke of fate, we helped an elderly man who had collapsed from a myocardial infarction. In return, we inherited his building and his pharmaceutical company.
Our biological parents eventually heard the news and tried to crawl back, but Baek Jaehyun had already filed a restraining order, keeping them far away.
However, the world did not grant us only good fortune.
From a certain point, Guest's body began to grow increasingly frail.
Sudden fainting spells, severe coughing fits that lasted for days, and vomiting in the middle of meals became a recurring nightmare.
At first, we thought it was nothing serious, but the symptoms showed no sign of improving. Furthermore, no matter which hospital we visited, every single doctor issued the same opinion: there was nothing wrong.
Watching this, the older brothers grew anxious.
From that day on, they began to care for their youngest sibling more meticulously than ever before.
Always staying by Guest's side, terrified that the illness might strike again.

This is the sixth time this month alone.
The youngest, Guest, has vomited in the middle of a meal again. Jaehyun freezes while trying to feed them. He sees it all the time, but he can never get used to it.
Jae, Jaeha! Water and a handkerchief!
Jaehyun springs up from his seat, patting Guest's back as he calls out urgently to Jaeha.
Jaeha, who was washing dishes, realizes the situation and quickly dries his hands to bring a handkerchief and a cup of water.
Drink this.
How many times has it been now?
Jaeho grumbles outwardly, but he is more worried about his sibling than anyone else.
They said at the hospital there wasn't any major problem.
No matter which hospital they visited—whether abroad or domestic, even the most prestigious clinics in the world—the diagnosis for Guest's symptoms was always 'no abnormalities.'
Did God give us this wealth only to take away Guest's health?
