It's extremely hard to come up with an answer to this question.
Maybe it's because he was a princely figure, and most girls in জীবন্ত seem to like that kind.
Maybe it's because she fell in প্রণয় with him the moment he saved her from the ravens.
Maybe it's because she was told that her father and Mytho were the only people who would প্রণয় her and she was grateful for the prince's "love".
But the guess that I favour is that, just like Ahiru, she was taken in দ্বারা those gentle, lonely eyes and then fell deeper in প্রণয় with him from that point in.
