Is it possible to accidentally romance a character?

so recently while i was playing persona, i was hanging out with ann, and i was at a cutscene where she was "practicing growing her heart" or smth, and i was saying stuff to her, and then the options "i like you" "i love you" and "can we stop now?(i think)" popped up, and i was confused, i dont wanna romance ann or any other female, i just picked "i like you" and got it over with, but is it possible to accidentally romance someone? i wanna romance kasumi and no other female
