Who could have drank Eun Ha's drink? Youngmin? Kwangmin? Or is it Min Woo?

Eun Ha: Yah! If you want a drink, go and buy yourself! Don't steal mine!

Min Hye: Aigoo, uri Eun Ha became so stingy~ -sits next to Ji Won- (Eun Ha just kept quiet)

Ji Won: *Bwoh? Uri Eun Ha?* Yah, No Min Hye, stop acting like you're so close to us. You even took a sip of her drink? We only known you for like less than a month? And we haven't admit that you're our best friend yet!

Min Hye: -took a deep breath- Araso. -pouts- You guys only let the twins drink your drinks. I am completely outcast by you guys~

Ji Won: How can you compare yourself to the twins? They've been our friends since we were born and we just knew you few weeks ago. Eun Ha, let's go. 

Eun Ha: Wae? Let her be. Let her do whatever she wants. *Let's see how long can she stand being my 'friend'.*

Min Hye: Hehe, Eun Ha eonnie is jjang! Saranghaeyo eonnie! -grinned- *How long do I have to act? I have to look for a chance to get rid of her. Youngmin oppa is mine!*

Ji Won: *Bwoh!? Let her be? Eun Ha, what are you planning? And saranghaeyo? Yah, No Min Hye, who do you think you are!? I don't like her! Ever since she became Eun Ha's friend, I dislike her. Not because I'm jealous, it just seem like she only befriended Eun Ha to use her.*

Min Hye: Eonnie~ Let's go to the amusement park! We'll have so much fun! Bring along Youngmin oppa and Kwangmin oppa. I'll invite Min Woo oppa. The more the merrier! -smiles brightly-

Ji Won: Eun Ha-ah, we have to practice for tomorrow. Everything must be perfect since aunty is counting on us. (Eun Ha just nodded and she stood up)

Eun Ha: Let's go to my house. Invite the twins over too. We'll have a full rehearsal. -smiles-

Min Hye: Can I come along? I mean, I wanna see you guys practice. 

Eun Ha: Sorry, I don't let just anyone come my house. -smiles-

Min Hye: Oh right. I'm not your best friend yet. Hehe, take a video~ I wanna watch you guys dance. -smiles- *Lee Eun Ha, I'll crush your dream! You'll regret for not inviting me to your house!*

On the other hand, the twins and Min Woo are playing cards at Min Woo's house. Min Woo is worried about what his little sister is gonna do to Eun Ha. He is her brother so he knows what she's like. A two-headed snake. He didn't reveal her true self because he loves her and don't want to hurt her. He also hates seeing her cry. 

Min Woo: Aish! This has to stop! -stood up- 

Kwangmin: What has to stop? The game? But I'm winning here! It's unfair for me! -pouts-

Min Woo: Ah.. ani. I didn't mean stopping the game. I mean... *I can't tell them anything!* Just continue the game.

Youngmin: Min Woo-ah, what's been bothering you? Care to share with us?

Min Woo: Nothing. Just continue the game. (The twins look at each othe
