In the house:

Luhan stands next to Lay, startled by the incidence. Witchcraft, is it? A house abadoned for a decade turned into something out of time, as if he time travelled. He has clearly never seen anything like this before.

But for Lay, things seem pretty normal. Facing unrealism isn't something new to him afterall. Infact, he in this house. 18 years ago, and now again. He's used to this place like his own home.

He looks around searching for Mrs. Oh, but there is no sign of her. He feels himself starting to get nervous.

Just then, there is a noise of footsteps in the stairs. An extremely peaceful face of an angel appears. Choi Sulli.

She comes hurtling down the stairs. Her face stricken.

"Lay, there you are!" her eyes speak of relief, "Who is he?"

"I am Luhan, Sulli." Luhan steps front, "I worked in SM, with you."

"And left later on. I remember you. But why are you here?" Sulli frowns.

"I want to help. I saw him lying outside in freezing cold. I couldn't risk to leave him alone."

"Oh.. But" Sulli turns to Lay, "How did you get out of the mansion anyway, Lay?"

"Grandma was showing me around. Suddenly, she got triggered in a conversation and left me outside." Lay glances at the front door. "For strange reasons, I couldn't get back in."

"What did you say to her?" Sulli's tone is slightly aggressive. Of course, everyone is bonded to that amazing woman.

Lay nods. Unsure of how to answer.

"She went straight to her room and locked the door. And she didn't look fine.." Sulli sighs, "Whatever you said must've hurt her badly."

"I'm so sorry for everything! But.. Sulli, don't you ever wonder why she has so many rules? So many secrets?"

"Well.. sort of.."

"Sort of?"

"I mean.. okay, I get what you mean."

"Good to hear. Because I need your support. I need to open that forever locked door and see what's hiding inside."

Sulli stands froze. Silent.

"I'm sorry that I hide that I know about that door and I convinced Yusi to give me her key. I was too late to realize you have all rights to know."

"Why didn't you just ask me for the key? Why did you have to get Yusi involved?"

Lay is surprised.

"I thought you won't want to-"

"I've been wondering what's behind the door for.. for I don't know how long!"

"Then why didn't you just check? You have a key, right?"

"I was.. scared." Sulli looks away.

"Of what?"

"I don't know, Lay. I'm sorry. All I can say is.. if you want to help, then we can find out the truth together."

"Thank you Sulli, really." Lay looks down to touch the key on his pocket, "Where is Yusi?"

"Asleep."

"And Grandma is on her room. Perfect. I think this is the time." Lay inhales.

"Will you unlock the door now?"

"Yes. Wish me luck."

Sulli's lips shake a bit, she's about to say something.. but pauses.

"Bless you, brother." she whimpers.
