(a/n: Long chapter because I love you all ^^)

Krystal sighed. She began to play with her fingers. 

"Ottoke?..." She asked herself. She slapped her face into the palms of her hands and cursed at herself. She had to leave or something was going to happen but she couldn't leave Yiyun alone practically drunk. 

She remembered the idiotic things Yiyun did the first time Krystal gave her the medicine. She smiled to herself as she realized that that moment was the first time she had begun to feel something for the blonde. 

"Krystal? I'm done...taking gah showerrr." 

Krystal dared herself to look up at Yiyun. She bit her lip as a handsome blonde with wet hair and adorable eyes sat down next to her. She silently hoped that Yiyun couldn't hear her heart beating. She reached for the tv remote and turn the tv on. 

"Awww...you're not gonna talk to mee?" Yiyun asked her. Krystal sighed and tried her best to ignore the incredibly attractive girl next to her. She glared at the tv and pretended to watch it.

"I want icecream..." Yiyun suddenly blurted out. She stood up and walked towards the kitchen. Krystal fought the urge to follow her and once she didn't feel the presence of someone else next to her, she exhaled deeply.

She had to minimize any interaction between her and Yiyun. That was why she didn't talk at all and turn on the tv.

"But how is it possible for someone to stay silent with their best friend that they secretly love?" She muttered to herself.

"It's not like she's going to remember anything..." Krystal said unconsciously. She then paused and widened her eyes.

Yiyun was practically drunk. Usually, people who are drunk don't remember anything that they did...

Krystal bit her lips. 

She'd betray Sulli if she did anything.

Krystal the decided that she had to get out of here before she did something a would do.

Before she could stand up, Yiyun returned with two massive bowls of icecream, each sloppily made. 

"Here." Yiyun said as she smiled a goofy and lazy smile and handed Krystal a bowl. She flopped down heavily and looked at the tv, not watching it. 

They sat like that for a while until Krystal reached for the remote again, completely bored. She went through different channels and decided to stop at a certain one.

"Oh, look. G(x) is having a live concert." Krystal muttered after taking a bite of her icecream. She read the bottom line for what they were playing.

"Beautiful Stranger." She read. Not one second after she said so, the music started playing. They sang for a while until Yiyun realized that it was g(x) on the tv screen.

"Hey there don’t be shy, talk to me.
Look into my eyes, beautiful stranger.
Don’t hesitate, hold my hand, take me, beautiful stranger." Yiyun sang along.

"You know that I’m different than them, look at my eyes, beautiful stranger.
Just like this, just like right now, it’s not strange, no." Yiyun sang. She stopped and smiled goofily at Krystal, who was staring at her.

"Whaaat?...I like thiiss ssong..." She slurred. Krystal looked away, realizing she had been staring.

"Heeheehee...Krystal?...look at meee..." Yiyun told her. Krystal ignored her and looked at the tv.

"Krystal?" Yiyun asked. Krystal gritted her teeth, trying to ignore her. She heard a sigh from the blonde and she thought she had given up. 

Suddenly, a firm hand gripped her chin and turned it towards the blonde.

"Stop ignoring me." Yiyun said as soberly as she could. Her other hand reached for Krystal's face and wiped the side of .

"Sorry Ssul..." Krystal whispered. Then she put her bowl of icecream on the table in front of the couch and pressed her lips against Yiyun's, her hands moved to the blonde's hair, pulling it and tugging on it as she tried to get a response. 

She did.

She felt Yiyun's lips matching hers as the blonde's hands pulled Krystal closer. Krystal accepted the pulling and pushed herself over Yiyun. She sat on Yiyun's lap and deepened the kiss. Her tongue swiped past Yiyun's bottom lip, demanding entrance and Yiyun gladly accepted it.

Yiyun's hands traveled from Krystal's back to her thighs where she slowly rubbed them, making Krystal moan gently. They were both getting quickly.

She won't remember. Krystal thought. I'm taking advantage of her...but why is she responding?...is it because of the medicine or...

She didn't get to finish her thought. She moaned loudly as Yiyun sent her lips down Krystal's neck. She bit it gently and it, her hands still rubbing the redhead's thighs.

Krystal, on the other hand, was deeply, her hands gripping Yiyun's hair harder and harder, pushing the blonde more into her neck. Feeling Krystal getting more aggressive, Yiyun bit harder into Krystal's neck. Krystal moaned and felt herself getting wet.

I shouldn't be doing this. She thought. 

She moaned again as Yiyun began to the corner of her chin, near her ear. 

But it feels so good...

Krystal felt Yiyun's hands move from her thighs to her back, lifting her shirt. She didn't remember her bra coming off but before she could react, Yiyun kissed each of them and looked up at Krystal, smiling.

"You're so y, Princess..." She said seductively. 

Krystal gasped as a rush of pure ecstasy filled her when Yiyun one of her s while her other hand massaged the other . Krystal, whose hands were still deep in Yiyun's blonde mess of hair, moaned louder than ever which drove Yiyun on edge. 

The blonde wanted to hear more so she bit Krystal's and pulled at it gently. 

Krystal gritted her teeth, trying to muffle the sound coming out of . She took deep breaths as she felt one of Yiyun's hands slid to her . It gripped it and just the idea that it was Yiyun doing this, she moaned again in pleasure.

"Yaah...did you hear that? I think it came from that apartment." Someone said outside. 

"What did it sound like?" Someone else asked.

"A moan." The first person said. 

"Maybe they're watching something they don't like." 

"No, it sounded ."

"Yaah, how would you know, eh?" 

"...s-shut up..."
