Question: who did aemon targaryen love?
Answer: - Maester Aemon to Jon Snow, A Game of Thrones. He could also have felt in love with someone at the 'unidentified' (maybe a planned trick by GRRM) lord's castle. This, potentially, could make the woman: Olenna Tyrell, some lady from House Hightower (lords of Oldtown), or some other lady from the Houses nearby Oldtown.
