Honestly speaking, I really don't like this pairing. I don't mind the age difference too much because of her mental age, but Rin needs someone who sees and loves her. All Ren sees is Erin. He's just loving Erin through Rin. Even if Rin was her past life, they're not the same anymore. Erin should have someone loves her as Erin.
why is no one talking about the so called ledgers? It was just filled with childrens stories. not a number in sight.
