Who might be?

There's this girl who loves to go to the library after school to read her favorite psychology book. She have a lot of friends but no one is interested in psychology that's why she's always alone in the library. "uhm hi?" A girl approach her. "oh my is that a psychology book???" the girl added with a hint of excitement in her voice. "Yes! How do you know? You read psychology books too?" she responded. "I love psychology so much of course, I'm Riri, and you?" Riri introduced herself. "My name is Jihyun, I'm glad to know that there are people who's still love psychology, like me" Jihyun exclaimed and chuckled. "Let's be friends? Since we're both a fan of psychology, we might get along" Riri gave a warm smile that made Jihyun do the same thing. "Well I won't decline that, my psycho friend" she laughed. "Sit beside me, let's read this book together" she offered and Riri nodded and sit beside Jihyun. The two became best friends, they're always hanging out together in break time especially in the library of course to read some books. Before, they will just meet on break time or after class, and now Riri is always in Jihyun's house. They're so close and feel comfortable with each other. Jihyun's POV I'm currently watching a movie and eating snacks when my phone rings. I thought its Riri but it's one of my friends, Gab. "Hello Gab, why are you calling me? It's already 11pm are you a vampire or what" I jokingly said. "You're the one who's vampire here lol, I just wanna ask, are you free tomorrow?" He immediately stated his purpose. "No, I'm with Riri tomorrow, why?" this guy is disturbing me, what does he want? "Riri? The girl you're always with?" he sigh but clears his throat after. "Yes but why you're asking me if I'm free? Are we gonna talk about something? Is that urgent or important?" I'm confused why would Gab suddenly wants to see me? Well it's been a month since the last time I saw him. Not gonna lie tho, I'm not being rude but I don't miss him even his presence. "It's not important, I just want to see you since you know it's been a while, Jihyun" what? He's voice soften? Or am I haluccinating. Our call has been disrupted by some knocking on my door. Who the hell will knock on my door this late?? "Let's talk later Gab, I'll just check who's outside" I heard him saying no but I ended the call idc. I put my snack on the table and pause the movie I'm watching so I won't missed the movie. I walk towards the door and twist the knob, well I'm not scared. "Who the freak are y- Riri?? Why are you here? It's already late gosh" I face-palm myself in disbelief. She's weird. "Helloo, I want to stay in your house if you don't mind it?" she pouted acting cute huh well she's cute I- what?? No what the hell I'm saying?? "Well I don't have a choice but to let you in but you shouldn't go outside it's late and it'd dangerous outside you know??" I shaked my head and open the door wide to let her in. "Waah you're watching a movie??? You could've call me! You're so selfish Hyunie!" yes, she's calling me that nickname and I hate it but she keeps calling me that. I'm not a fan of nicknames but I can't with this girl. "I'd rather watch alone than to watch with you, you're so talkative and annoying" I tease her but it is not true but her reaction is cute. "Hey I am not talkative" she shouted while folding her hands across her chest. See?? Isn't she cute I can't believe I'm saying this but yeah I can't control it We spend the night together and watch three more movies and yes I forgot to call Gab again, I assume that he didn't wait for my call again. . . . . I woke up in the morning I stretch my arms and look around but then I remember that Riri slept beside me, where is she?? Did she go home? I immediately stood up and go downstairs to check if she's still thete and there she goes, she's cooking... What? "Wait I thought you already go home? And why are you cooking?" I scratched my head. "Well I want to say thank you by making you a breakfast and I'm also hungry, and it is disrespectful if I just disappear duh" she rolled her eyes on me, wow just wow this girl got some attitude huh. Riri's POV After we eat, we talk about the movies we watched last night. We're laughing when someone call her phone. Who's that? Early in the morning? Really? "Oh wait excuse me, I'll just answer this call" she excused herself leaving me behind. Maybe I should ask her later. Jihyun's POV I walked outside and answer the call btw it's Gab. "Hello-" I was cut off by him "Hello Jihyun??! Are you okay?!! Did someone barged in your house?! How are you?!! Someone snatched you? What?? Tell me??" he asked me a tons of questions is he freaking out? Well of course I didn't call him last night so maybe I made him worried. "I'm okay" That's all I can say since I didn't understand his questions and my brain is still not functioning lol. "Oh well I'm glad" I felt that he's in relief and satisfied with my answer I guess. "Anyway I have to go talk to you next time Jihyun" he added and didn't let me say goodbye and end the call. "Hyunie!" Riri called my name and I look back to see her. "Are you going home?" I asked so I can drive her home. "Who's that?" she asked me. "The one who call me? He's Gab, my friend, why?" I walked inside my house and seat on the couch. "A friend? Really? No friend will call you early in the morning" She roll her eyes again for the second time, I swear I will pierce her eyes if she won't stop. "He's just worried because I didn't call him last night. We had a call last night then you knock and he thought that it's a snatcher or what and I end the call immediately to open the door so yeah" I explained it to her, and I got an idea. "Are you jealous?" I asked playfully. "NO, why would I?" she shakes her head and sit beside me. "Don't worry you're my bestest friend" I smiled at her "As you should duh" she stand up and wear her slippers. "Wait you're going home? Let me give you a ride" I offered. She agreed and then I take her home safely See you tomorrow, Riri
