To survive him when they first met, she had to pull away from her fear and build new habits - this is self discipline in he beginning, after some years probably she overcame it, because he interacts with her like a totally different person, he’s obviously not there to torture her and doesn’t threaten her
i suppose we should imagine he ordered her death, because if he actually proceeded himself, it would certainly becomes a huge plot hole -

They’re living different lives now. He’s practically a different person from the one who ordered her death. Years of experience change people. He hasn’t lived through years that would make him become the cold hearted man that he was. He’s taking a different path and becoming a different person, as is she. Like how going to one college will introduce you to completely different classes, teachers, and people which affects how you become in the future but if you go to another college you will again go through different experiences and become different once again.
Blushing to someone who killed u in ur past life (⊙…⊙ )
