That seemed tobe the case overall. Considering that Tiltu is just lonely and miserable, she only calls him hubby because she desires a connection with others. She's too immature to understand love in a romantic sense, so she's treated more like an adorable little sister character. Which is why I don't count her. That means that main girl is only girl. And best girl.
Now that I think about it, he doesn't even look at the other females the same way at all. While at the same time, he's having lovey-dovey moments with the main FL constantly.
I feel like almost everything on the island(including the island itself) is trying to get these 2 together. He literally had a vision of the main girl holding his future child. It's like the entire island is screaming, "WHAT ARE YOU DOING, MAN!!?? WIFE HER UP RIGHT NOW!!" Or something like that.
