Tora Ziyal and Garak's relationship age difference

Rewatching DS9 at season 4, episode 5, and the age difference is alarming. She was 13 when found by Dukat and maybe 15 when she started living on DS9, while Garak is well into his 40s. It's kind of creepy The dynamic between Ziyal and Garak definitely raises some eyebrows, especially given his complicated past with her father. Why Jake was not considered as a love interest.
