I get why author did the ending like that for the side couple. It’s like an open ending so I’m just gonna imagine the omega got new partner who love him wholeheartedly, and have more kids, so the omega and shitty alpha can just be coparenting. Even when alpha change his name, nahhhhh won’t go back with him unless the omega is stupidooopidooyabedabedoo. Even in the next life and next and next, I’ll make sure my imagination will not let the omega and shitty alpha be together. ╮(￣▽￣)╭
