riku

You attend a famous high school in Korea. You are a beautiful girl with short hair and a mole on your nose. You are cheerful, like to joke around, and play around in class. You have friends named Carmen and Ian; you're always together and are best friends. There's also a boy in your class named Riku. He's someone who really likes to joke around and tease you; he always teases you and annoys you. Actually, Riku likes you, but he doesn't want to tell you that he loves you. You don't like Riku; you only consider him a friend who likes to joke around, but even so, you still play with him and joke around with him. Sion is Riku's friend; he's a pretty handsome guy, but he's also like Riku, very fond of teasing you. And there's also Sakuya. Sakuya is Sion and Riku's friend; Sakuya also really likes to tease you. You could say that the three of them always tease you and make you angry.
There are also students named Ni-ki and Jungwon; they are boys who really like to joke around and tease each other, just like Riku, Sion, and Sakuya. There are also students named Heeseung and Jay; they are the class president and vice-president, with Heeseung as the president and Jay as the vice-president. There are also quiet male students, Sunoo and Sunghoon; they never play around or fight in class.
One day you go to school and when you enter the classroom you sit on your bench waiting for Carmen and Ian to arrive. While waiting, you're just playing on your phone and taking photos. Only you, Sunghoon, and Sunoo are in the classroom. A few moments later, while you're taking photos, you see someone behind you. You're a little surprised when you turn around and it's Riku. You're annoyed with him, and he sits at the desk in front of you. He starts chatting and joking with you... and what happens next?

While chatting with Riku, Riku only joked and mocked you, and sometimes he told stories about the horror he experienced.
