Okay, so from what I understand in the story is that, the snake is a rare species, the rabbit is an aberrant species. The wolf needs to mate with a rare species in order to inherit the family. The wolf doesn't want to because well, he sees the snake as a friend (and he doesn't want to, pretty evident every time he choose the rabbit) but the snake sees him as his fated one (there's a chapter where the red string from the snake is connected to the wolf). Unfortunately, the wolf fated one isn't the snake but the rabbit.
What's infuriating about this is the way it was illustrated. Because every time I feel that the wolf and snake pairing would sail, the rabbit appears and then obviously the wolf would choose the rabbit cause they're fated. It keeps giving hope but I should have known from the chapter where the wolf gives a fake snake to the rabbit instead of his friend snake when the rabbit ask him for it. I should have known, it wasn't because he treated the snake as someone special. He sure treated him as important but not special. I'm also angry when the wolf keep the snake from being with the hamster dad if he would only be with the rabbit in the end. Like I know, the hamster dad did leave them before but it's more painful seeing your one-sided/rejected love happy especially since once upon a time it could be you.
I thank the snake for being lovely and friendly cause he was okay with it. He accepted it and move on with it. He is still friends with them but I lowkey wanted him to go far away from them (╥﹏╥)
And that chapter where his children say goodbye to him, damn, how many children will the snake see off before he die? Is that foreshadowing that he will be alone and not end up with the wolf???
Anyway, that's how I understand the story.
