We can't be friends

I know

No one's pov:

By now all of the students know that Heejin and Hyunjin are dating. Those two would walk through the hallways together while holding hands, eating together during lunch and Heejin would even go far as to offer her a ride back home. Hyunjin really is liking this treatment from Heejin, she felt so love and appreciated and her feelings for Heejin just grew more day by day. It has been 1 month in a half since they started dating.
It's 4pm now, Hyunjin is in her student council office checking up some paperwork until Choerry bursted in the room.
"Yerimmie? What's wrong?" Hyunjin stand up as she get close to Choerry helping her to sit down as Choerry take a big long breath and look at her sister seriously with a sad face. Hyunjin notice that Choerry is sad, "what's wrong sis?" Hyunjin ask as she gently cup her sister face. Choerry can't help be feel even worse, "Hyunjin unnie... Do you love Heejin?" Choerry ask, Hyunjin was stunned by the question as she then chuckle "yes yerimmie I've been in love with her ever since middle school, even though at that time I didn't even realize I love her". Choerry feel even more guilty now, "Hyunjin unnie, do you trust me?" Choerry ask Hyunjin sincerely. "Of course I trust you" Hyunjin reply with no hesitation. Choerry then take a big breath as she told the news to Hyunjin. "Hyunjin unnie... Heejin unnie is only using you to win a bet with Yves unnie" Choerry finally blurted out while closing her eyes. After a few seconds of silent, Choerry opens her eyes to look at her sister, she's shock at the tears that is falling from Hyunjin's face. Hyunjin don't even know how to react with the news, she's heartbroken, all of it have been just lies made up by Heejin , but what if there's another reason behind it, Hyunjin love Heejin so much she wishes it's not true. Choerry just hug her sister trying to comfort her as Hyunjin can't hold her tears anymore.
At around 6 pm it's already time to go home but Hyunjin is still in the student council office alone, she told Choerry to go home before her since she still have some work to do. Hyunjin can't even focus in doing her work, she can't stop thinking about Heejin, and at that moment Heejin enter the student council office. "Hi baby" Heejin smile as she look at Hyunjin as if she's so in love. Hyunjin can't help but start tearing up again when she saw Heejin. She just stay silent while she let her tears fall in front of Heejin. "Hey why are you crying?" Heejin ask in a worried voice as she got close to Hyunjin and kneel in front of her as she wipe her tears. Hyunjin can't help but feel even sadder,  "Am I that easy to be played with Heejin?" Hyunjin ask in between her tears as she looks at Heejin.
