Who is Bronya's love interest?

Excuse me, could you clarify something for me? I've been reading about this character named Bronya, and I'm curious about her romantic interests. I'm trying to get a better understanding of her character and her story. Could you tell me, who exactly is Bronya's love interest in this narrative? Is it a character that has already been introduced, or is it someone we're yet to meet? And if you don't mind, could you elaborate a bit on their relationship and how it affects Bronya's journey? I'm really invested in this story and would love to know more.
