Hitomi and Hyewon is studying together at the library. Hyewon teaches Hitomi how to solve some math problems easily but Hitomi seems don't understand anything because she was spacing out 

"Hitomi did you get it?" Hyewon asked while tapping her ballpen on notebook pointing the math problems

"Ah--- ah... Yeah i understand"

"You don't understand anything don't you?" Hyewon look at her disbelief

"Is there any problem that is bothering you? Just set it aside now you will failed in this subject if you don't focus." Hyewon added

"Im sorry unnie." Hitomi muttered 

"It seems that you can't focus at all so tell me what is that problem?"

"A---ah... Ummm" Hitomi is hesitating and fidgetting her fingers

"Come on tell me i won't tell it to anyone okay? Im good at keeping secrets." Hyewon smiled to Hitomi

"Promise me that you won't tell it to anyone okay?"

"I won't i promise." Hyewon said and raise her one hand 

Hitomi just breath heavily and sighed

"There is a person that i like ever since high school and she is nice to me. She always protects me she also helps me when im having a problem and she's always by my side lately she's been acting weird and being a lot clingy to me. But i don't think she likes me the way i like her because she just treat me as her little sister."

"Is that person is Chaewon?" Hyewon asked

"Ho--- how did you know unnie!"

Hitomi is about to raised her voice but Hyewon stopped her

"Please be quiet where in library."

"Im sorry unnie."

"But how did you know that the person im talking about is Chaewon unnie?"

"Just considered that im good at reading people's mind. Anyway i just sense it because you're always with Chaewon and you two are disgustingly cute together being lovey dovey why don't you confessed to her?"

"I don't think i can confess to her." Hitomi said and hung her head low

"Why?"

"Because i think she likes Eunbi unnie or Minjoo." Hitomi said with a sad tone 

When Hyewon heard certain name she chuckled lightly she's about to laugh hard but she remember that she's in the library so she just look at Hitomi with a serious and expressionless face

"There's no way she would like Eunbi unnie. Because Eunbi and i are dating."

"Eh? Is that true unnie?" Hitomi's eyes widened and look confused on Hyewon

"Yeah it's true. We were dating for more than a month we don't tell it to class because it will cause some issues and problem that Eunbi the almost perfect student is dating a lazy bug, food addict, and a weebo like me. So keep it a secret between the two of us okay?" Hyewon said while smiling to Hitomi

"Okay. But i think she likes Minjoo." Hitomi frowned

"Minjoo? Hmmm for Minjoo she didn't always hang out with us because she's from other class maybe Chaewon is just being to her."

"Really?"

"Yeah. You know Hitomi you're problem is like a math problem you just have to solve Y axis to get the value and interms of X axis the value of Y not necessarily in pure constant form but it's the form of X" Hyewon said and write something on her notebook

"3y+ x=7 if you solve that problem you can find the answer that you've been looking for now let's continue to study."

"Thank you for cheering me and also for helping me unnie." Hitomi said while smiling at Hyewon

"You're welcome. Now let's continue you have to solve that problem first."

"Yeah"

As the two of them continue to study and Hitomi is now focused on her studies as she gets what Hyewon teach to her. And it's already 6:00 pm they need to go home because library is closing already and it's getting dark

"Hitomi are you sure you don't want me to walk you home?" Hyewon asked

"Yeah. It's okay Hyewon unnie also you help me with a lot of bunch of things i don't want you to bother this time by just walking me home besides my home is just near here." Hitomi replied

"Okay if you're that desperate then i will not walk you home. But be careful okay?"

"Yeah." Hitomi smiled to Hyewon to reassured that she's fine on her own

"I will go now don't forget the things that we study okay?" Hyewon said and started walking but Hitomi called her and Hyewon stop walking

"Hyewon unnie thank you again."

"You already said that so many times. No problem im happy that i can help you i will go now." Hyewon replied and walk off

When Hyewon dissappeared to Hitomi's sight. Hitomi started walking heading home

"Maybe Nako and Hyewon unnie is right that i should confessed my feelings to Chaewon unnie." Hitomi thought to herself 

As she walk heading home she suddenly stop from walking as she breath heavily then sighed

"Okay i will do it!" She suddenly scream out of nowhere with a confident voice and continue walking heading home

Meanwhile Hyewon is walking as she reach the bus station she saw Eunbi sitting on the bench. Hyewon come towards to her

"Hey what are you doing here?" Hyewon asked

"Obviously waiting for you! What do you think im doing here hanging out alone by myself?" Eunbi replied

"Sorry."

"It's okay. Let's wait for the bus to come here i will you home." Eunbi replied and Hyewon suddenly grab her wrist and start walking 

"Yah where are we going Hyewon?!" Eunbi asked

"Im hungry let's go grab some food." Hyewon replied still holding Eunbi's wrist

Eunbi tap Hyewon's hand signaling Hyewon to let go of her wrist. Hyewon let go of her wrist Hyewon look at Eunbi dumbfouded but Eunbi grab her hands and intertwined their fingers together

"We can hold hand like this when were outside the school. It's not like all of the people here is our schoolmates." Eunbi said while blushing lightly

"Sometimes i don't understand you Eunbi unnie." Hyewon chuckled

"How many times do i have to say that you can call me Eunbi when it is just the of us!"

"Sorry okay i will call you Eunbi. But it is okay if i can call you Eun?" Hyewon asked while looking at the flustered Eunbi

"Call me whatever you want but don't call me with that nickname when were in school get it." Eunbi replied

"Got it. Now let's go"

Hyewon and Eunbi are now walking together holding hands as their fingers are intertwined together

"I want to eat in a buffet restaurant im so hungry."

"You're really a food addict. Okay if you want we can there"

"Yay!"
