Soomi POV:

I didn't mention the flashback to anybody. I was planning to mention it to Jinyoung but we always had schedules. Family Outing ended a while ago. *I've gotten close to Changjo and he gave me his number. Same with Sungyeol and L, L acts extremely weird when I'm around. Like.. the way L.joe did. I don't know if that's a bad or good thing. It's like he knows me, but yet he didn't. Maybe I knew them both before, I got into the accident. I forgot about the accident. I honestly wish I could get my memory back, because life isn't the same when you only know half of your life. I wish Appa found a way to get it back...* I thought. We were on our way to Wonderful/B1A4's practice room.

It was a couple of weeks until the fall special. We were learning our singing for our comeback soon. It was sooo exciting. We're heading to the studio to reharse. Appa told us that we were going to be doing a couple dance with a another boy band. He wasn't sure yet so he didn't say who. We were sooo excited. 

(Yesterday) 

Jinyoung POV:

I’ve been called up to Appa’s office. *Did I do something wrong?* I thought.

“Jinyoung, you and B1A4, are doing a special stage with F(x), in about 3 weeks.” My eyes widened.

“Appa, did you forget? F(x) were Soomi’s girlfriends.” His eyes widened and he shook his head. “Their CEO called me and asked him to do it because I owe him a favor…” He said.

“Can you cancel?” I asked.

He sighed. “I’m afraid not..” He said. “I’m sorry Jinyoung.. I forgot.”

“It’s okay. I’ll work something out. When is our practice?” I asked.

“Tomorrow.” Appa said and I nodded.

“Wait. There’s even worse news… Wonderful has to do a stage with either Teen Top, Infinite, or Block B.” Appa said. My jaw dropped.

“I didn’t know which one so I decided to ask you.” He said.

I sighed.. *It can’t be L.. Jaehyo isn’t a good choice… Okay.. I trust you L.Joe.* I thought. “Teen Top.” I said. He nodded. 

 

(Skips to today) 

We were in the practice room practicing for Baby Goodnight and then 5 girls walked in. 

"Annyeonghaesayo. F(x)-imida." They said. Their eyes were all glued to me. A trainer walked in.

"Annyeonghaesayo JongHyun-imida. I'm your cheorographer for this dance. Your pairings are Krystal, Jinyoung. Sulli, Gongchan. Amber, Baro. Victoria, CNU. And Luna, Sandeul. Go to your partners and I'll start with Sulli and Gongchan." He said.

"Jung Jinyoung, who has a little sister named Soomi? Sounds very familiar to me." Krystal said. 

"Really? That's strange." I said with a nervous throat. She grabbed the collar of my shirt.

"Dude, the jig is up. We know about you and Soomi. It's been years since we heard from her." Krystal said and tears were forming from her eyes. I felt bad because I took my best friend from her.

"Jonghyun hyung. I'm going to take Krystal to the restroom." He nodded. I took Krystal outside of our practice room and near the bathroom. She started sniffling. 

"I haven't heard from her since the f(x) group decision. She didn't keep our promise of being together forever.. She joined another group! It's like she's a completely different person." She said. I felt even worse. *I'll trust her.* 

"Okay... The reason is.. After the F(x) CEO meeting, Infinite had to go to the U.S. You knew right?" She nodded. 

"That's why me and Hoya broke up." She said.

"L didn't tell Soomi. And she got into a car accident." I said. 

"S-She got hit?" I nodded and held back my tears.

"She got amensia. She didn't remember anything from her past. Not even me. But after 2 years, we, me, my dad, B1A4, and Kyumi helped her remember us. But we didn't want her to remember you guys, infinite, or teen top, not even block b, because who knows what will happen... She will be very hurt on what L did to her." I said. Krystal was in shock.

"B-but, why not us? We never did anything bad to her." She said. 

"But, it might bring up things involving infinite. And then L. And I didn't want her to remember someone like L.Joe who will leave her for fame.." I said. She nodded.

"I understand... Can I tel F(x)?" She asked. I nodded.

"But not anyone else." He said. She nodded. 

We walked back into the practice room and then, we heard loud voices outside. *Uh-oh.* I thought. 

Soomi POV: 

"Annyeonghaesayo Unnie." I said to the unnie in the office. She's really nice.

"Annyeonghaesayo Soomi, your oppas in the practice room if you want to see him." She said.

"Neh~ Maybe later. Kamsamida." I said. She nodded. We all headed to the recording studio on the other side of the building. Jinyoung saw us go there and he sighed in relief. 

"Okay. You girls are having a change of concept." Our music producer said.

"J-jeongmal?" I said. 

"Your song is called Flashback (By After School). It's about a girl who keeps getting flashbacks of her old lovers. She wants to prove to him she still loves him." he said. We nodded.
