After Krystal had left, Moonbyul felt lonely and lost. She had no one to talk to and she had no other plans for the day. She would text Solar but she remembered how strange and weird she was acting yesterday. Come to think about it...why was Yongsun unnie acting differently? Moonbyul thought to herself. She wondered if she should check up on her or just let her be but if she let her be, she didn't want her to think that she doesn't care about her anymore. Moonbyul was in a dilemma. 

To: Yongsun unnie
Unnie, are you okay? I just wanted to check up on you...you were acting so weird yesterday, is something wrong?

Moonbyul deleted and retype her text 3 times and finally she pressed send. She sighed to herself and hailed a cab back home. Around 15mins later, her phone vibrated in her pocket. That must be Solar, she thought. And it is.

From: Yongsun unnie
I'm fine, thank you for asking.

That's it? Moonbyul was taken aback by her short yet straightforward reply. It was obvious to her that something was up. She wasn't going to let this matter go easily so she made a plan to keep an eye on her starting tomorrow onwards.

Krystal POV

I know I told myself to make a change and smile more often but once we reached the airport, I couldn't help but show my "straight " face. Everyone was getting in our way and it made me tensed. I've always hated being in crowded places or when everyone's eyes were mainly just staring at me. I took a deep breath and let out a forced smile. "UNNIE! YOUR SMILE IS BEAUTIFUL, PLEASE SMILE MORE!" I was surprised after hearing that out of blue. Just then I remembered Moonbyul said the same thing too earlier on. I then turned to the fan and gave her my warmest and sincere smile which made that fan really happy. I turned back, still smiling and entered the departure hall, leaving all the screaming fans and paparazzis outside. Just thinking about Moonbyul made me happy and I couldn't stop myself from recalling the time we spent together this morning. "Yah! What's with that smile?" Amber sneered while punching my arm lightly. I snapped out of my thoughts and shot a death glare at her through my shades. I was just too lazy to put up a "fight" with Amber now so I walked away first leaving the llama behind.

We board our flight and...ugh great, Amber is sitting next to me. I was hoping Vic unnie was my seating partner because most likely she'll be sleeping throughout the whole journey and it's a good thing because I get to look back at the pictures I took with Moonbyul unnie without trying to hide it from anyone. I sighed and turned at Amber who looked back at me "now what?" she said and I rolled my eyes and looked away. She couldn't see me rolling my eyes but she knew me well enough to know I did that. I heard a "tsk" sound from her and it actually made me want to laugh because I realized my actions were driving her nuts and she would probably not tease me anymore for now. I unlocked my phone and the first thing I saw was my scandalous selca with Moonbyul as my wallpaper. I panicly lowered my screen brightness and I almost dropped my phone during the process. I forgot that I had set it as my wallpaper and i'm just glad no one had seen it. But I spoke too soon, "Who's that?" my eyes went wide open looking at Amber "Wh-what?" I was caught off guard. "Who's that on your wallpaper? I've never seen that friend of your's before. She looks familiar though, do I know her?" Oh crap, great. I knew Amber would ask this load of questions, she had always been a busybody but..in a good way I guess? She's always the one I end up spilling my secrets to. But I trust her, she had never told my secrets to anyone and she was always there to hear my rants and stories. She might be an sometimes but she's still someone that I hold close to my heart. "He
