Leviathan theory #5
The reason Levi became obsessed with Ruri-chan was because he spent years thinking that his soul mate didn’t exist. He had waited for eons with no sign of them. He wanted someone to love him and he played an game where he was the main character and he had to woo Ruri-chan. She was the first to make him smile so she would always be special to him. When his soulmate does come along, they will understand Ruri-chan took care of him before they could arrive and he will love them more for understanding that.
