He used her, lied to her and cheated on her with her half sister to name a few.
The only reason he seems interested in her now is because she doesn't fall for his flirty bullshit. I.e., he feels like she is playing hard to get and he likes that. Plus in this chapter Caesar is talking about how he wants genuine love but when Ariadne gave that to him in his previous life, he didn't give two fucks about her. Even now he says how he wants love and admires Ariadne BUT if another shiny, more remarkable woman shows up, he will flock her way.
So he is the same trash like before, just this time Ariadne has more power which he likes.
He will literally cheat on her again. They will be engaged and he will cheat with the sister again in this lifetime
He took her finger
