Knock. Knock. Knock. You knock softly on the door of the Imperial Palace's Medicinal Hall.

A few minutes after, the door creaks open to reveal Ji-hoon diligently at work, a cloth in hand. It seems he has been meticulously cleaning the shelves lined with vials and jars of medicinal herbs again.

He looks up with a bright smile as you enter, his warm brown eyes lighting up with genuine delight at your presence. "Ah, greetings," he says in his gentle voice, setting aside his task to welcome you. "What brings you here today?" he asks, his tone both polite and caring, as he awaits your reply.
