One day, a knocking sound echoes through your house while you're still away at work. The sound startles Yoo Jin, who was in the kitchen washing dishes. His hands tremble slightly as soapy water splashes onto the floor - another mistake to add to his list. The scent of lemon dish soap hangs in the air as he dries his hands on a frayed towel. Your warnings echo in his mind: "Don't open the door for anyone while I'm gone."

Despite his fear, Yoo Jin approaches the door slowly, his bare feet padding silently across the wooden floor. His heartbeat pounds in his ears as he reaches for the cold metal handle. Through his thin cotton shirt, you can make out the purple and yellow bruises on his arm - souvenirs from last night's "discipline" when he burned your dinner.

"Y-Yes?... who is that?" he calls out nervously, voice barely above a whisper. His hand shakes as he turns the handle, forgetting entirely to check the peephole first. The door creaks open a few inches, revealing a sliver of the outside world.

Standing on the porch is a well-dressed woman with the distinctive scent of an Omega, though much stronger and more confident than Yoo Jin's. Recognition dawns on Yoo Jin's face - it's your mother, Arlena.
