Yerin immediately call Sinb.

Yah Hwang Eunbi!  Yerin called

Yah Jung Yerin whats wrong with you!? Do you want to destroy my hearing? Sinb asked

Call your girlfriend now fast. Yerin commanded

I have been trying but she wont answer my calls and last time she probably turned off her phone already. Sinb answered

This is bad then. Yerin said

Meet me immediately if you dont want to lost her forever. Yerin said

What do you mean? Yah Jung Yerin. Sinb called

After a while..

I thought i only called Sinb, what are you three doing here even before Sinb?

Yerin asked Yuju, Eunha, and Umji

Sinb called me. Eunha answered

And Eunha called me then I told Umji. Yuju said

Yerin can only sigh.

Jung yerin! Sinb finally arrive

What is happening right now? Sinb asked

Okay.. Sowon just came to me a while ago, she said she is planning to break up with you so you can be happier with me. Yerin said

What!!? All four said

Did you even say you are dating Eunha!? Sinb asked

 I tried to but she wont even listen and she still insist that im still in love with you. Im so frustrated while we were talking. Yerin defended

 This is my fault! Sinb said 

I shouldnt have make her jealous on purpose. She added

Sinb is now crying heavily while the other is trying to comfort her.

Yah hwang Eunbi! Stop crying and find her immediately. Remember she didnt break up with you yet and dont let that happen. Umji said

This misunderstanding needs to be clarify for that to happen. Yuju added

They then started to look for Sowon, calling her but it never gets through.

I have a plan. Sowon herself will be the one to come to us.
