They smooching...

Yerin frozing on her spot. Her eyes as if almost pop out from it sockets, she having hard time to hold her urge to shriek out loud.

That guy tightly embraced Sowon's slender waist. Their faces stuck together. Seemed enjoying their fondle.

Yerin's legs suddenly feel weak. She flopped down on the floor, leaning against the wall. Her heart beating rushly, her mind in mess. She just doesn't get it what actually happen. 

Who is that guy?

What his relationship with Sowon Unnie?

Yerin never imagine witness that kinda side of Sowon. As if she totally stranger...

Sowon yelped when she take turn at the isle and find Yerin there, it's like dejavu, but once again she quickly regain her sense back then squat in the front of Yerin who still gawk dumbfoundingly.

"Yerin-ah. What are doing here? Are you stalking me?" Sowon calmly ask.

Yerin shake her head, there's nothing voice can come out from , so instead she shows plushy toys that she get from the claw machine.

"Ah, you were from the claw machine?" Yerin nod.

"Was it the same goes before?" Sowon ask again, and Yerin nod again.

"C'mon, let's get back to our waiting room, it's about our time to perform." Sowon said then get up. She offer her hand and Yerin just give her hand to her and let her Unnie pull her up and drag her back to their waiting room.

After that --- the second --- incident, Yerin is just like dumbfounding person for the rest of the day. She still shock, and hardly regain her sense back, fortunately that condition is not effecting their group performance, Yerin still able to perform without make a single fault, since performing is already become her natural habit, she just let go herself, she able to  instinctively sing, dance, and making face expression during their performance, since her body remember very well the order. But of course her 'weird' behavior is confusing her members, except Sowon of course, but she just doesn't say anything.

Later, when they finished their schedules and get back to their dorm. Yerin having difficulty to sleep. She just can't stop to think about that day incident. Even after few hours later, Yerin still awake.

The dorm is in silence. Every members already on their respective bed and sleep, but in the dark Yerin just staring at the ceiling, unconsciously blink sometimes.

"Yerin-ah..." suddenly Yerin heard Sowon call her.

"Uhmm~..." Yerin respond absentmindedly.

"You can't sleep?"

"Eung~..."

"Is it because of me? Because what you saw I did?"

"Eung~..."

"Are you angry?"

"No."

"So?"

Yerin sigh deeply, "I just... shock. Terribly shock."

"..."

"Who's that guy? Is he your boyfriend? Why you not tell us? Is CEO-Nim know you dating someone?"

"No."

"So?"

This time Sowon is the one who sigh heavily, "I'll tell you all when I'm ready."

"When?"

"For sure is not now." Sowon's tone is starting sounds irritate.

"..."

"Go to sleep, Yerin-ah."

"Unnie, you scary. I'm scared to you."

"You scared to me?"

"It's like... you suddenly become stranger to me. When before I thought we close to each other, that I know you very well. But turns out I don't know you at all. And you doing something that I can't understand. I feel lost. You used to be my dependable pillar that always I can count on. One of limited comfortable people for me that used to be I can talk to and share my real opinion or my sincere feel. But now... you are scary for me. You become mysterious, unpredictable. I feel insecure.'

"..."

"..."

"You just find out the other side of me. But this is still me... You can talk to me like you used to be."

"..."

*****

Time after time...

Yerin having hard time to get back to her usual feeling to her unnie, she keep feel awkward to Sowon. Other members can sense the weird situation between their eldest unnies, it effecting their group chemistry also become awkward. But since they don't know what the cause, can't find the reason, also never witness them fight for even once, it makes them really confuse. Then the 4 youngest members decide to holding secret meeting to disscusing about their Unnies matters.
