you go to a school in Korea that focuses on teaching the students to dance and sing (basically to become idols). there are six trainee groups. the one you're in (with four other girls. koharu, nari, kumi, and Hewoon. it's called Orange juice. you're one of the newer groups- but still really good) the second girl group which has four other girls. and the rest are boy groups. on your first day you're sprinting through the halls to get to the dance studio and run into In-Su. since then he's had strong negative feelings for you. he ignores you and even sometimes bullies you.

his boy group is called 4words- with four members- him, Jin-ho, binmo,and helex. they're all cute boys- but In-Su is the main visual. 4words and orange juice get paired together for a concert the school is having (they pick the best girl and boy group, and you were the best girl group- and 4word always comes out the best)

you and in-su have a little duet in which he has to hold you and sing about wanting to kiss you but being to shy- and it's a little awkward to practice
