As Tia said the Ruve now is a totally different person,he took a different path,exactly like Tia did,so I cannot see him as the same Ruve of the first path
Oh of course, his development is based on the MC's trauma after all. Dimension Breaker
I think both of them found a new dimension and changed lots not focusing on just one thing(she was obsessed by him,he was obsessed about the lack of love from his parents and envy of her)
