Nayeon pov

The second I got out of jeongyeon's room, I saw somi waiting. She saw me crying and she immediately came to hug me.
"Unnie, please stop crying. We came here to have fun, not to cry. Come unnie let's go to our room." Somi said as she guided me because I couldn't really see anything from my blurry eyes.

I really wanted to go to her and comfort her, but something inside me said that she needed to be alone now. I was about to leave her alone until something surprised me. Jeongyeon unnie climbed the rail and she was on the other side of the rail now. I was praying to God that she wasn't going to do what I thought she would. I immediately started running as she took off one hand off the rail, she had only one hand holding on. I was running so fast likey life depended on it. Everything was slow motion. I was so close to jeongyeon unnie, then I saw her take off her hand off the rail causing her to fall. I was still running, hoping I could catch her. I caught her. Barely. I was holding her hand so tight I think the blood circulation stopped in her hand. She was heavier than me and I wasn't rea
