"Good morning auntie! Good morning uncle!" Yuju greet SinB parents 

"Oh Yuna ah,good morning. Come here and join us for breakfast" SinB dad pat the vacant next to him and Yuju obey him

"So,what are U doing here? I thought U suppose to be at school right this time?" SinB mom ask

"I'm here to pick SinB like always" Yuju smile make both of SinB look at each other in confusing way

"But Eunbi has go to college already Yuna ah" SinB mom word make Yuju shock

"Really? With who?"

"Moonbin" SinB dad said

"Moonbin?" SinB parents nod

"She didn't tell U? *Yuju shake her head* "But she said that she already told U,that's why Moonbin is here to pick her up" SinB mom word make Yuju getting more shock and she get up from her seat to go to college. Not before bow to both SinB's parents

As soon as she arrive at her college,Yuju immediately run to her class to find SinB but to her disappointed,SinB's not there. She go to student council meeting room after that. And there she saw SinB was laughing while linking her arm with Moonbin. Yuju look at them while clenching her fist tightly,she can't thinking straight anymore,she just storm toward Moonbin and SinB then grab SinB wrist make SinB startled

"Yah! Let me go! It's hurt!" SinB try to yank her hand away from Yuju grip but Yuju didn't even bother to let her go

"Yuju ssi,she ask U to let her go so ple-" *punch* Yuju punch Moonbin cheek hardly make SinB hit her shoulder

"Yah! Why did U do that?" SinB angry and was about to help Moonbin get up but Yuju drag her to college backyard

As soon as they've arrived at the backyard,Yuju loosening her grip and SinB immediately hold her own wrist to lessen the pain that Yuju cause

"I'm sorry baby,I didn't mean it" Yuju try to heal SinB wrist but SinB yank her hand away 

"Don't touch me" SinB said coldly make Yuju startled

"But I'm sor-" 

"What do U want?" SinB said in her cold way

"I just worry about U,I go to your house but your parents said that you've go to college with Moonbin already" Yuju explain with soft tone

"So?" SinB said still in cold tone

"Why U didn't tell me?"

"Why should I?"

"You're my girlfriend and I should know where U going"

"So what's the different with U?"

"Huh?"

"Tsk! U thought I don't know that you're with Hoshi at gym yesterday?!" SinB said angrily 

"But what is th-"

"Why U didn't call me? Why U didnt inform to me first? I'm your girlfriend too!"

"I'm sorry,I forgot to tel-"

"Of course you're forgot to tell me,well you're having a great time with your ex boyfriend right?" SinB said and crossing her arm below her chest

"Ex boyfriend? Who are U talking about?" Yuju ask confusedly

"Tsk! Pretending to be a stupid? Just stop your acting Choi Yuna,I already know about all your action"

"Acting? Action? Can U just tell me straight to the point?"

"Heh! Think about it by yourself" SinB was about to turn around but Yuju hold her arm to stop her

"Wait! I'm the one who should be mad bcoz you're going out with other guy and what's more worse is U even linking your arm with him!" Yuju said angrily

"Are U jealous?" SinB ask lazily

"Yes I am! Who'll not be jealous if their lover was going with other guy"

"Just go hell with your jealousy. Like I care about it" SinB said nonchalant

"Yah! What's wrong with U? What has that Moonbin guy said to U,till you're becoming this way?"

"Don't drag him in here!"

"I should! I have to drag him bcoz I'm sure he said something bad about me until U became this cold to me!"

"So what if it's true?!"

"SinB listen here" Yuju try to make SinB look into her eye but SinB didn't move at all make Yuju surrender "Ok,I dont know what is the hell he was talking about me but let me tell U something,Moonbin is love U and I'm sure he'll say many things bad about me to U,which it is not true! At all!" Yuju said firmly make SinB face her with cold stare

"At least he love me sincerely and not bcoz of desperately to get someone love" SinB said coldly and walk away leaving Yuju in frustration and confusion

During in their class,SinB didn't look at Yuju at all even just a glance she didn't spare for Yuju. And their friends seems like there's nothing was going wrong with them,but they just couldn't describe it,so they decide to think about it together during their recess

"What's wrong with U and SinB,Yuju ah?" Eunha ask in concern

"Nothing"

"Don't lie" Umji said firmly

"Did U hurt SinB heart?" Eunha ask while squinting her eyes

"No! I'm not,she's acting so weird since yesterday" Yuju said sadly

"Since SinB was not here,can U tell us the whole story?" Yerin ask and Yuju start telling them the whole story from her conversation with Moonbin until to the backyard

"Until now,I still couldn't figure it out why she hate me" Yuju whine and slam her face to the table. All of her friend just look at her in pity and confuse at the same time about SinB attitude 

Meanwhile SinB was with Moonbin in student council meeting room having their lunch. SinB doesn't feel like wanna eat with her friends today bcoz she know that Yuju must be there tok and she didn't ready to face Yuju after their argument at backyard

"Hey,why U didn't eat your lunch? U don't like it? Want me to change it for U?" Moonbin in concern

"No,the food is just fine" SinB said lifeless

"Then? Is it about Yuju?"

"Yea,I'm just thinking,is it true that Yuju and Hoshi used to be a lover before bcoz Yuju seems shock when I said about Hoshi being her ex boyfriend" Moonbin chuckle make SinB look at him weirdly

"There's no a thief admit he's a thief SinB ah,same goes to your Yuju,U think she'll just admit about her faults? Someone like her will never being a honest SinB ah and U did a right thing by ignoring her" SinB didn't say a thing but just stay silent and eat her food

'It's the same food that me and Yuju used to ate together but why does it didn't taste the same? Maybe bcoz she's not here to feed me' SinB said in her mind
