(THE INTRO IS KINDA SUCK AND DIFFERENT FROM WHAT I HAD IN MIND 💔 BUT ANYWAY, HERE WE GO)

Seungmin is your brother's friend. He's at the same age as your brother — 17, which means they're in high school while you're just 12, a kid.

He often comes over to your house, mostly to hangout with your brother in his room. He sometimes teased and bothered you as any annoying brother would. However, you developed a crush on him despite acting annoyed when he bothered you whenever he came over with your brother.

As times go by, he starts to notice that you have a crush on him so he purposely treats you like a kid even more knowing how much you hate that, and calls you his little sister to emphasize that he sees you as nothing more than just a little sister to him. Drew a clear line that you should never cross.

Years later — After graduating, he had gone to continue his studies in Los Angeles along with your brother. You have never heard from either of them ever since. They're probably 24 now, and you're just turning 19 and already got into high school. You had grown so much, that even your little crush on him was either buried deeply inside and forgotten or completely disappeared. Until on a random monday, you just come home from school and are surprised by your brother's sudden return and Seungmin is also there... standing across the couch, looking at you with a small hint of surprise on his face to see how much you have changed/grown.
