I Realize I've Painted Circe In A Horrible Light But It's What Happened Canonically - Tumblr Posts
How did the model react to Roman retaliating against his parents? How did he handle that?

Circe loved it, though didn't openly show her joy when Roman fought back. The two had been having a secret relationship for years right under the noses of his parents, back when Circe was old enough to begin work as a model and Roman still a young teenager smitten with the first positive attention somebody gave him. She held Roman back from beating his parents to a bloody pulp, knowing that being convicted of murder would result in him being heavily punished by the law therefore losing Janus Comestics since his parents were still the owners of the company. It wasn't out of love or concern for Mr and Mrs. Sionis. Circe been working on wrapping Roman around her little finger for years, knowing his parents would one day replace her with a younger, fresher star once her looks began to fade. Beauty doesn't last forever and, in the world of fashion, there are always beautiful women to be found much like one would find plenty of fish in the sea. She loved the money and fame, the ease of her work in only needing to look beautiful to keep a healthy paycheck coming in. She knew it wouldn't last forever, but it could last longer perhaps, if Roman took over Janus Cosmetics and she became his partner. Circe pretended she was remorseful after the incident, that she'd end the relationship with their son once she had seen him out. Unable to bear losing their top model just yet, Mr. and Mrs. Sionis bought her lies and it was all Circe needed to enact the next stage of her plan. Roman hated his parents, she'd known for years but that night, his willingness to acquiesce to her words was the sign she needed to know he'd go to any lengths to please her and concocted a plan with him the morning after. The next night, the family home of the Sionis's burned down with his parents somehow having become trapped in the blaze. Smoke inhalation was thought to be the cause of their deaths, although their bodies had been burned too badly by the fire for pathologists to tell for certain. Circe provided Roman with an alibi and, although he had not been officially named as heir, ownership of Janus Cosmetics fell to him anyway due to being next of kin, a legal process that would be finalized by the time he was 18. Circe was very pleased with how everything had turned out, and while perhaps it happened a little sooner than she'd have liked, everything went according to plan, at least for a few more years until trouble hit Janus Cosmetics.
