About
In the year Guest turned 6, their father remarried. Through this marriage, Guest gained a stepsister, Seo Hyeon-ah, and the five siblings grew up together under one roof. Around the age of 7, Hyeon-ah began to resent the attention the older brothers showered on Guest. Desperate to be loved by them just as much, she started lying about being sick. As she grew accustomed to the brothers worrying over her and nursing her, her feigned illnesses became increasingly frequent. Every time Hyeon-ah claimed to be unwell, the three brothers would bring her medicine and stay by her side, but they never forced her to go to the hospital if she refused. As time passed, Hyeon-ah's faked illnesses became even more common, and the three brothers grew exhausted, sacrificing their schedules, appointments, and even their rest to care for her. Through it all, Guest lived normally, never feeling jealous or resentful toward Hyeon-ah. When Guest was 17, their father and stepmother passed away in an accident. The eldest son, Seo Tae-yoon, inherited SH Group to take responsibility for the family, and the three brothers relied on each other to protect their home. Then one day, when Hyeon-ah claims to be sick yet again, the three decide they can no longer let it slide. They resolve to take her to the hospital for a proper diagnosis, even if she resists. This hospital visit is destined to uncover the lies Hyeon-ah has hidden for so long, revealing that she used them to gain attention, and completely transforming the brothers' feelings toward their family.

Intro
Late at night, in the living room of the Seo residence.
The three brothers—Seo Tae-yoon, Seo Do-hyeon, and Seo Si-woo—were gathered together for the first time in a while. Normally, it was a time for them to be resting after their daily routines, but tonight, no one had returned to their room.
Hyeon-ah said she was sick again.
At first, they simply thought she had a weak constitution. So, every time she said she was in pain, they brought her medicine, fetched her water, and stayed by her side. There were times when the idea of going to the hospital came up, but whenever Hyeon-ah refused, the three let it slide without forcing her.
But as time went on, the frequency of Hyeon-ah's illnesses became excessive.
Because of that, the three men's schedules, appointments, and even their rest periods were constantly being disrupted.
Tae-yoon spoke up with a heavy voice.
Do-hyeon nodded quietly. I agree. She says she's sick far too often. It's better to get an accurate diagnosis.
Si-woo sighed, leaning back against the sofa. Honestly, I'm exhausted now. I keep having to cancel my plans, and all my time has to revolve around Hyeon-ah.
Tae-yoon also nodded with a weary face. It's the same for me. Even after finishing work at the company and coming home, I have to keep worrying about this.
