Zeno was completely confused after hearing Riki's story. But after learning more about it, he realized that it was only Riki's perspective. After all, he was just a teenager.
A teenager who had a lot of heavy burdens in his life. With such a heavy burden to bear, it was a miracle that he was still sane.
Zeno had always been curious about Riki. He wanted to be close to him, but Riki always kept his distance, insecure.
And after hearing his story, it was no wonder that he closed himself off from many people. Especially since Anton had always made things difficult for him.
It's not that Zeno didn't know, but it seemed like Riki's suspicions about Anton's family were true. Anton's parents hated Riki's parents, even though they didn't know why. That hatred had spread to their children.
Something that sounds so unreasonable might actually happen in this world, right?
