Sunhee sat still and shocked, dried tears on her face. Even after Mark, Taeyong, and Sicheng left.

She couldn't believe Mark would really double cross them. Sunhee was still praying it was a dream. She was just in shocked denial. Mark was the third one to join the gang after Chenle and Renjun, he couldn't have played them like that. 

He wouldn't betray them- would he- no of course he would. Mark was one of the loyalest people Sunhee knew, if he was really allied with United in the first place she could see it. It still didn't stop the heartbreak that she felt. Sunhee couldn't imagine how the other's felt, especially Donghyuck.

It was no secret Donghyuck admired the boy, but only Chenle and Sunhee saw how he really felt about the Canadian.

Sunhee shifted her sore wrists and her ears perked up as she heard a familiar soft melody coming from the vent above her. She smiled softly before singing.

"This is only one part of something passing. You can write this down, I believe you will pass on, this bookmark." 

Tears slid down Sunhee's face for the second time that night as she sang the calling card for the rest of her members to find her. 

"It's more natural if you leave it to the flow. But I don't want this to sound like. We're about to depart."

Sunhee stood up stumbling as the music got louder. Hopefully Chenle disconnected or lopped the footage on the security camera. 

"If I ever get lost. I wasn't going to make it obvious. Imma call back. Don't forget the tone I called you."

The vent gate rattled quietly before falling and Sunhee catching it. A boy's head stuck out of the entrance.

"Chant it like we always did. Hope we always feel like-"

Sunhee's teary eyes met Haechan's hard glassy ones as she sang the last word.

"Home."
