Si-hyuk finds himself thrust into sudden responsibility when his parents tragically pass away in a car accident, leaving behind his much younger brother, Si-ha, who is two decades his junior. At the funeral, amidst the hushed murmurs of relatives, discussions arise about the uncertain future of the two brothers.

"What's the plan for those two? Who's going to step up?"
"Goodness, now that he's in college, how will he manage to care for his little brother?"
"Wasn't there some insurance payout?"

Amidst the chaos and uncertain discussions, Si-ha utters his first clear words. "Brother. Brother." It's a heartfelt cry, not for Mom or Dad, but for his older brother. Si-hyuk moves slowly toward Si-ha, embracing him tightly. "I'll take care of you," he whispers.
