Chaeyeon laughed manically and stood up raising both of her hands as she screamed "Yes". 

Of course, that was only in her imagination. In reality, she stayed seated with a smug. 

- So... - she began to say to Hyunggu. - This is surprising. I thought your final answer was no. - 

- I changed my mind. - Hyunggu responded. 

- Can I know why? - 

- Does it matter? - 

- Oh, no. Don't get me wrong. Your reason to do it won't make a difference to me. I just want to know. - 

Hyunggu sighed and told Chaeyeon what Minji had said to him. 

- So she threw a little bone at you and it changed everything. Wow. - 

Chaeyeon smiled pleased. As she had said, it didn't make a difference to her what were Hyunggu's reasons to accept but she liked that it would be easier with his help. 

- Then, now that I'm in, maybe you could tell me what you planned for this. - 

- Yeah, ok. - 

Chaeyeon searched under her bed for her notebook. She had placed it there along with some of her favorite candy. A hidden place that was not so hidden since her brother definitely knew about it. It just meant it was off-limits. Not that Jaehyun took her stuff without permission. You could just say it was like a habit of hers. 

- Here it is. - she showed the notebook but Hyunggu frowned upon looking into it. 

- There's nothing written here. Just "Plan A". -

- Getting you on board was the first step of the plan. I haven't really planned anything besides that. - she said. 

- I thought you said you have. - 

- No. It's not an easy task, Kino. We really need to get a clear and good idea of what we're going to do. Or do you think I've done this before? - 

- No offense, but, with the carefree way you talked about breaking them apart gave me the impression you have done this before. - Hyunggu said with a soft smile. 

- Well, you're wrong. This is my first time. - 

- Got it. So, what are we going to do? 

- We're both smart. And two heads think better than one. Let's come up with a plan together. - Chaeyeon suggested and Hyunggu nodded. 

They sat right next to each other in silence as they stared blankly ahead for several minutes. Nothing came up. 

- We don't have to get the plan right now. - Chaeyeon said. 

- Yes. How about we sleep on it and let's see each other tomorrow. - Hyunggu told her to which she agreed. He then proceeded to leave. 

After he was gone, Jaehyun came to Chaeyeon. 

- What was that about? - he asked. 

- Nothing. - 

- Nothing? I've never seen you talked to each other. Then he took the blame for the banner. And now he comes to our house. Do you like him? -  

- No, he's not my type. We're... study partners. - Chaeyeon replied. It was the same thing she told Hyunggu's Dad so it made sense to her saying it to her brother. 

- Study partners? Come on, Chaeyeon. I know you. I know something is happening and... you know what, nevermind. I don't want to know. - 

Jaehyun walked away convinced it was better not to know whatever that was going on with his sister and Hyunggu. She'd ask for his help if she was in trouble so he was not that worried. 

Yes, Chaeyeon was not in trouble. Yet. And she was not worried either. She was enthusiastic about the next part of her plan she had come up with during the night. So the next morning she spent the whole day waiting for the time to have the chance to talk to Hyunggu. It finally happened after they finished their cleaning duties. 

They went to sit on a bench in the patio and Chaeyeon ignored all the curious looks they got while Hyunggu took notice of every single one of it but didn't say anything as she didn't react at all. 

- Did you think about something? - Chaeyeon asked Hyunggu as she opened her notebook where she had written down her ideas. 

- Not necessarily. I spent the night trying to not back down from this. - 

- What? Don't tell me you chickened out. - 

Hyunggu gave it a thought and shook his head. 

- No. I'm still in it. Did you come up with something? -     

- I did and it's quite simple. If we want to separate them by showing them they're not right for each other, we first need to find out what they liked about the other. They're so opposite so there must be something in specific that they liked. Sure, they are probably attracted to each other cause he's hot and she's hot. But there must be feelings there. -

"And feelings change in a heartbeat." 

- Oh, right. That's a very good idea. - Hyunggu said. 

- I know. -  

- But, how are we going to find out? - 

- That's even more simple, Angel. We'll ask them. If you want to know something you have to ask. I will ask Rowoon and you will ask Minji. - Chaeyeon answered. 

-  Wait, do you want me to ask Minji directly what she liked about her boyfriend? - 

- Of course not. You can't go and ask her directly because then she'd be like: Why do you care, you ? - 

- I don't-I don't think Minji would say that. - 

- She may not say it but that's what she will think.
