<human>: So here's some back story, I'm a senior in high school and i have around two months until i go to college and recently i noticed i started to get feelings for my friends younger sister. She's going to be a junior in high school next year. I noticed i can make her laugh effortlessly, she smiles at me often when we see each other in school and whenever she needs help she always ask me to come along with her. However, i have been her brothers best friend for ten years, and i'm not totally sure she likes me back so what does Reddit think i should do.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I like my best friends younger sister but i'm going to college in august and don't know what to do. (also apologies for poor formatting it's my first post)
