On the other side:

Luhan rushes out with car key striking off for Lay's neighbourhood house. While driving he hurrily calls Seulgi and explains the scenario.

Seulgi gathers the rest of them for a meetup and tells everything Luhan said.

"..so Luhan decided to go there and he's probably taking him back." Seulgi concludes.

"I think that's the best idea. We should've not let him go alone there at first place." Joy says.

"May both of them be fine," Yeri sighs, "Luhan hasn't called after that, Right?"

"No," Seulgi replies.

Just then, Seulgi's phone buzzes. A message from Luhan.

"I found him unconscious, lying outside and freezing in cold. I've took him back on my car but he doesn't seem to wake up yet."

Seulgi's face turns cold. Irene squeezes her hand.

"He'll be fine." Irene says patting Seulgi on shoulders.

"I don't know what to say of any of these," Joy sighs, "I just don't understand. Remember lay said he met Yusi? Yusi died so many years ago! How?!"

"Oh yes.. I had knocked him and he said he's playing with Yusi." Yeri joins.

"So he really did meet her?" exclaims Joy.

"Why didn't you tell before?" Seulgi asks Yeri.

"I'm sorry.. So much happened that it slipped out of my brain."

"Don't get attached to Yusi, Lay.." Wendy whispers very gently, and a teardrop falls from her eyes.

However, it was still enough loud for most of them to hear.

"What did you say, Wendy?" Irene asks.

"Wendy?! What's going on? You know about this?" Joy asks.

"Wendy please say!" Seulgi requests.

"STOP IT YALL," Kris yells and everyone goes silent, "Stop pressurizing her."

"What's happening?" Seulgi asks.

"What's happenin' is happenin'.. and everyone gotta face it head to head. Stop pushing this girl seriously." Kris replies.

:

Lay wakes suddenly to a loud click and finds himself in the passenger seat of Luhan's car.

Luhan looks up from fastening Lay's seatbelt, and a look of intense relief washes over his face.

"THANK GOD YOU'RE OKAY! Just sit tight.. I'm getting you out of here, don't worry." he says.

"No! I've to stay!"

"Look, I don't know what you think happened in there, but I found you lying outside, half frozen.. I think you're still in shock. We need to get you to a hospital."

"I'm NOT imagining things or making these up! It's all real!"

Luhan puts an uncertain hand on Lay, his eyes sympathetic.. but disbelieving.

"If only there was a way to prove it all happened," Lay says sighing.

..Then his hands goes to the pocket where he kept the antique key.

"Look at this! You think I just happened to find a polished key like this lying there?"

"I..don't know! How did you get it?"

"Yusi gave me."

"As in Baekhyun's dead sister Yusi?"

"Yes, the very same. She's trapped in that house along with 2 other people. I to help her."

"Help her? But you came here to find your own answers."

"Luhan, that's exactly it."

"Huh?"
