"Yes, look there's something I wanted to talk about.."

"Let me guess.. is it about Dawn? And the door?"

"It is. And more importantly, that key you showed me.."

Yusi gets surprised, "What about it?"

"Do you think I could maybe borrow it?"

Yusi looks uneasy, and her hand goes to the pocket where she keeps her key.

"I don't think so.. Mrs. Oh said not to unlock the door."

"Yusi.. I to know what's behind that door."

"What if it's a.. ghost?"

"Then I'll find a way to deal with it. Better than being afraid, right?"

"Um.. I want to say yes, really, but.."

"Mrs. Oh?"

"Hmm.. she was very emphatic about it. She takes so much care of me. I don't think I can- betray her.."

"Yusi, I know you have reasons. But see, I have reasons too. I'm also very emphatic about this house."

"Yes, I noticed that-"

"There's something really weird going on here that brought me here. And I need that key to find out what. I'm badly trapped. Can't you help me have a better life?" Lay requests with innocent puppy eyes.

"I want nothing but the best for you, dear friend!" Yusi sighs, "Well.. I don't know what to make of any of this.. but I guess I want to help you."

Yusi pulls that antique key from her pocket and pushes it across the table to Lay.

"Thanks Yusi. I promise, this will all make sense."

"Promise me whatever you find out, I'll be the first one to know it."

"I promise."

Just then, Mrs. Oh steps into the dining room, and Lay quickly slips the key out of sight.

"Oh.. Hi, Mrs. Oh!" hesitance on Yusi's voice.

Mrs. Oh narrows her eyes suspiciously, "Someone looks guilty.. What have you two been upto?"

Yusi gets nervous and unready to the plot, gives a slight glance at Lay for help.

Lay rescues from being caught.

"We were doing music!"

Yusi adds in, "Mr. Zhang was helping me with a music I was working on."

"That must be wonderful for you, Yusi.. to have another Musician friend." Mrs. Oh smiles gently and rolls eyes at Lay. "Would you come with me for a moment, Lay?"

"Of course."

Lay follows Mrs. Oh out to the foyer, where she pauses before the main gate.

"Lay, have you heard of someone named Oh Sehun?"

"Yes.. I have."

"Where is he now?"

"South Korea. He is my colleague, a member of kpop group EXO."

"Why did no one tell me.."

"Is he your nephew?"

"No! Why'd you think that?"

"I just thought. Cause of surname, maybe.. Why are you getting anxious Grandma? Calm down."

"He could be my son, or grandchild, or other relations too.. why you thought of nephew."

"Cause-" Lay pauses.

("Sehun ran away, he is trying to hide from her, there must be a reason. I wonder why is she disagreeing he's her nephew?" Lay thinks to himself.)

"Cause?" Mrs. Oh asks.

"Nothing."

"Lay.. there's a secret place I want to show you."

"Secret place?"
