Advice pls?

Okay so the other day after our football game one of our team managers(my age) was drinking a coke and when she was half full and the game finished shes like “u wanna finish it? Im sugared out today” and i accept it but the. Later on the bus we were taking to go home (her stop is the one right in front of mine and usually its just us on the bus for 15 mins and the entire time she was talking to me like actually being fun (usually she is loud annoying and not rlly likeable) then when her freind saw me walking home next to her cause we live sumwhat near eachother ger freind was like “awww cute couple” and she just went quiet and put her hood on and walked faster. Today at practice she again offered me the rest if one of her drinks but didnt offer to anyone else. And on the bus ride home today she was like doing all the “whats ur fav…” questions. Also whenever shes walking ahead of me she like makes her butt shake more when she walks or sum idek but like idk if thats how she normally walks. Whats going on here does she like me or does she think im a freind or what?
