Joy was so shocked that she dropped the piece of paper on the floor. She quickly pulled out her phone and messaged Sungjae.

Joy: Oppa

Sungjae: Yea?

Joy: The note... did you put it into the paper bag?

Sungjae: Note? What note

Joy: It wasn't you...

Sungjae: What wasn't me? Did something happen? 

Joy: Nothing, nevermind

Sungjae: Ya Park Sooyoung, what is it you better tell me

Joy: It's nothing, I saw a note in the bag so I was wondering if it was from you, but if not then I guess a fan probably put it in without me knowing

Sungjae: Oh, aish you scared me Park Joy! There's nothing I should be worried about right?

Joy: Nothing, I'm fine don't worry

Sungjae: Okay good, did you eat all of your food? 

Joy: Yup, it's really delicious, thanks oppa! Anyways I gotta go now, I'll talk to you later

Sungjae: Okay, talk to you later Sooyoung-ah, muahh~

Joy put away her phone and stared at the note. 

I know your secret.

Who could it be from? What secret is it about? If it's not from oppa then who put it in? Is the secret referring to my relationship with oppa...?

Joy was panicking, she was so distracted that she didn't even realize that they have already arrived her next schedule.

Manager: Sooyoung, Park Sooyoung!!! Hello? Earth to Joy? 

Joy: Oh? Unnie

Manager: We're here now, get off the van

Joy: Okay

Manager: What's with your expression? What has gotten you so distracted?

Joy: Nothing, it's nothing...

Joy got off the van and prepared for her schedule. She tried to convince herself that it was probably just a prank from haters, but her mind kept drifting back to that note and what it meant. That night, as she got off the van and walked towards the dorm, even though it was just a very short distance that she has walked on everyday, it seemed exceptionally creepy and scary. She peeked behind her and rushed towards the dorm. She jumped at the smallest sounds. Joy quickly ran to her room and locked the door.

Who could it be? And how did this person know about my secrets...??

Joy was so frightened that she didn't even realize Sungjae has been calling her. While Joy was concentrated on trying to figure out who could possibly slip in the note, Sungjae was growing increasingly worried about Joy who wasn't answering her phone. 

Did something happen? Why isn't she picking up, she said she'd be done with her schedules by now... Is she okay? I've overthinking this, she's probably so tired that she just fell asleep as soon as she got back... Aish, that sleepy head

But Sungjae kept getting a feeling that something isn't right. Finally, he grabbed his coat and headed out. 
Wendy opened the door as Sungjae rang the doorbell. 

Wendy: Oh? Sungjae? I didn't know you were coming, Joy didn't tell us you'd be coming today?

Sungjae: Sorry I came without notice, I was worried because Sooyoung isn't answering her phone, is she back yet?

Wendy: Yes she's already back, she was back quite a while ago, she was acting a little weird though

Sungjae: Do you have any id
