By this way, they film their music video for another three days as Hyeri wants to make this music video as awesome as possible.

They can't even have the proper rest. And they don't know what happened to her today, she left the house so early together with Sojin unnie to find a swimming pool so that they have to cancel the shooting for today.

So they decide to play in the largest room of Chorong.

" It's so hot here."

" Ahh?? I don't think so."

" Unnie, open that door. I want to go out to the balcony."

Namjoo asks for Chorong and the leader nods her head at Namjoo. She then walks to there and opens the door.

" Chorong unnie, I think - "

" Yes?? "

Suddenly, Naeun calls Chorong and she turns around while she opens the door. At that moment -

*  CRACK  *

" AHHHHHHHHHHHHHHH "

" Unnie!! "

" What happened!!?? "

When all six of them run towards Chorong, they see a broken into pieces pot.

" How did the pot reach here??? "

" Yes. They have no brain. When someone open the door, it can fall onto the head."

" It's so lucky, unnie."

Chorong seems she is so afraid. Her face is as white as a paper.

" This must be a closed door. So they put the vase. That's all."

She said as she wants to calm down the girls. And they forget about it later. In the evening of the next day, they all decide to ride bicycles on the beautiful grass. Then Namjoo starts the drama.

" What about we have a bicycling race?? "

" No. It's so scary."

" And dangerous too."

" Chorong unnie~~ Please. Only for once."

Finally, everyone force Chorong to agree and she has to nod her head at the end. For the referee, they pull Jihye who came to play with them.

" Start is from here and the end line will be that big tree at the end of this hill. Ready. One  Two  Three."

It is not an important case but they all ride as fast as they can to win. Suddenly.

" Ahhhhhh, the brake is broken!!! "

" Chorong unnie!!! "

They don't know what happened to Chorong's bicycle but it runs down along the slope with a high speed. Bomi stops her bicycle and she runs towards Chorong but the older girl is far away from her reach.

" It must be the brake."

" There is a chasm in the front."

Hyeri who is watching them shouts.

" Chorong unnie!! Hit that tree!!! "

Chorong follows Hyeri's words and she hit the tree. She falls onto the ground and Bomi reaches her.

" Unnie, are you alright??? "

" Yeah. I think."

She said. At that time, the other members are also there and they take Chorong back to the house. But Hyeri pulls back Namjoo and Hayoung.

" Wait up, kids."

" What, ajjuma??? "

" See."

" Huh?? "

They all widen their eyes when they see sharp cut which looks like slide of blade on the brake string.

Time is passing by slowly. Chorong goes back to her room since she has had her dinner and thinks about the two accidents that she has faced today. She thinks they are not ordinary cases.

While she is thinking, she suddenly remembers about the diary. Is this because of the books???

But Sandara seems she will not harm her. Namjoo's family is a little complex. But she doesn't think there is someone who wants to kill her in this house.

Uncle Ji Sukjin is on his trip again. Then Son Jihyo unnie??? She is the only one who knows that the diary is in her hand.

Oh no. Does Jihyo unnie wants to kill her??? But she doesn't think so.

While she is thinking, she heard something is being knocked. She looks around and she sees a shadow who is thin and tall at the balcony faintly.

" Who are you??? "

Chorong asks that shadow but the shadow doesn't answer so Chorong moves closer to there and open the door.

" Where it goes??? "

That shadow is gone. Chorong suddenly afraid and she closed the door in fear. She sits on the bed and she doesn't dare to sleep that night. When she goes down to living room the next morning, almost everyone is in there.

" Unnie, are you ill??? "

" Imm. I was sleepless last night."

" Wae unnie?? "

" I saw a ghost."

" What??? "

" How?? "

" I will tell you. When I close the door, I saw a shadow. When I went there and check it, there is no one."

" Then it really is a ghost??? "

" How it looks like?? "

" Ahh, Eunji-ya. Why you want to know about it?? I think it is tall and thin."

" Are you serious, Chorong-na?"

" Aww, Sandara unnie."

Sandara enters the room together with Jihyo while they are carrying plates of apples.

" The person you said looks like Heechul oppa."

" Yes??? "

" It can't be, Sandara. Son can't be."

Jihyo unnie said while she is frowning. But Sandara said with a certain tone.

" But it can be Heechul oppa. I have dreamt about him these days. He is with a sad face. He doesn't like strangers touching his stuffs. What did you do in his room??? If you take something from him, you should give me. He wants to warn you, I think."

" I didn't do anything."

" Sandara unnie. Please stop. What are you talking about??? "

Namjoo stands in front of Chorong and she stops Sandara.

" There is no way of my brother being a ghost. And don't talk to Chorong unnie like this."

" Namjoo-ya."

" Don't you dare to talk to my members with that manner. I don't like. Please go back. Go now."

Sandara seems she looks surprised. She takes her bag and goes back immediately. Jihyo unnie follows her. But Nana unnie and lizzy seem they don't understand a thing so they have to explain them starting from the pot thing.

After they have finished, Hyeri who has been playing the game said.

" Chorong unnie, you should explain to us."

" What??? "

" You have something to hide from us, right??? "

Everyone silently wait for what Chorong will say.

" I have- "

Chorong paused her words and she looks them. She sighs as she realises everyone is concentrated on her.

" I have nothing to hide from you. That's enough. I will go read."

" Chorong unnie. Wait."

But Chorong ignores them and she goes up to the upstairs. Eunji said.

" Don't you think Chorong unnie is a little strange. She really has something to hide from us. "

" What do you want to say??? "

" What if the accidents are planned and someone is trying to kill her??? "

" Kill??? No way! "

" Yes way. The pot falls off for no reason. The brake is cut. And she saw a ghost. They are not ordinary."

" The brake is cut?? "

" Yes. We found it, too."

This time, Namjoo and Hayoung said. Eunji said with the tone that looks like Sherlock Holmes.

" What if the ghost she saw last night is a real man??? "

" This is what I want to say."

Hyeri said while she is clapping for a few times.

" But we have a problem. Chorong unnie doesn't want to tell us what she is doing. This accidents are all aimed at her, so there must be really something."

" What should we do??? "

" We are going back in five days so we have to follow her everywhere and watch her every steps so that there will be no dangerous for her."

Bomi suggests as she is too worried for her unnie. All of them agrees with her and they make a plan to watch Chorong secretly.
