"I miss Ssul," Krystal said sadly

"Stop it Soojung! Don't you ever dare to mention her name again," Amber said seriously.

"Is it wrong for me to miss my bestfriend? Or I can say my twins? Is it wrong?," tears started to form in her beautiful eyes. Their memories were too precious to just forget about it. Her heart instantly arched when reminiscing their memories before.

"She's not worth our tears Soojung. If she really loves us, why she must choose that man instead of us? We're the one who stay beside her all this while. But what did she do? She left us! She left her family!" said Luna emotionally.

This time Krystal can't prevent her tears anymore. She cried hardly to the point her shoulders shaked because of uncontrollable sob. Luna's words hit her. Sulli really left them.

"Enough girls. Soojung, wipe your tears. Today is our 6th anniversary. In this beautiful day, why must we spill our tears? 6 years ago, this is the path that we choose. So all the pro and cons we have to accept it. Maybe Sulli was just meant to be with us for 5 years only. Hopefully, she get her happiness that she want. As for us, let's continue to soar the sky and make f(x) become stronger than ever," said Victoria.

All of them nodded their head. Krystal slowly wiped her tears. She reach something behind her.

"Happy 6th anniversary f(x)! I love you!" Krystal said excitingly while bring a cake.

Victoria, Amber and Luna were surprised.

"It's so wonderful Soojung. Do you bake it by yourselves?"

"Of course."

"Since when do you know how to bake?" Luna said teasingly.

"Do you forget that I always stick beside Ssul when she's baking? I learn it from her of course," Krystal said casually without noticing that she's mentioning their ex member.

The other three silent afterwards. Krystal bite her lips when she notice her fault.

"Fine, let's make a wish girls," Victoria said, breaking the silent. She lit up the candles.

The girls closed their eyes and silently make a wish.

"Everybody done?" Amber asked.

"Yes"

"1, 2, 3 f(x)!"

They shouted their usual chant before blew up the candles.

Without noticing, there's someone behind the door who heard everything. That person clutch while tears rolling down swiftly. A box fell down from her grips. She ran away.
