i think it's basically impossible for her based on how she was raised. she was trained from a young age with the sole intention of surviving - and winning, least she be raped and killed (she was raped in the novel by several people). even if she's now thinking of marriage, i doubt it has anything to do with romance - merely "people are happy, once i am done with my role here i will pick up a new role." her entire character is very mechanical, without that much passion other than serving.
but yeah, i do wish she would start to feel something - even if she doesn't realize his majesty loves her (why would her god love her, after all?)
she was raped by one man only, her commander back when she became a soldier. She fought and avoided being raped by Lucius men, so that statement is hella wrong.
But she was abused (mentally, verbally, physically) by several people. It took 10 years of hard work and determination for her to be "respected" as a knight.

Loving this Manhwa but I do wish she would start to notice the emperor as a man. Although him being rejected all the time is totally funny. I'm not expecting her to suddenly become a blushing maiden but I do wish she at least realize the "jokes" she thinks he's making are earnest.
