<human>: Mine: An upperclassman that I knew since my first year in college always took really good care of me and he was always like a big brother to me. One day, I decide to go to an apartment party with a friend. I had been texting the upperclassman the entire day about random stuff and my friend teases me about it, saying maybe there's a thing between us. I dismiss it, because he's always been a big brother to me. Then, at this party, the police come and I get scared since I was still underage at that point. I text the upperclassman and he gets really worried about me, saying that he'll come over and drive me home. Now keep in mind, this was about 4am, and I was all the way across town. At this point, all the stuff my friend had been saying gets to me, and I think... Could there really be more to this than what I've been thinking?

Silly me gets my hopes up and after I get home, I thank him and all. His reply? "No problem... You're my little sis after all."

Can you give me the gist of the text in a nutshell?
<bot>: I kinda started to have feelings for a guy who was like my big bro, but it turns out that he thought I was like a little sister too.
