Why did they have to add the sibling-obssed agenda lmaooo it was good to see their children but it's a surprise it came to that

Can I just say that Zeno and Kuro was completely random??? I thought it was gonna be a Zeno taking care of a much younger spirit but nooo they had to add a last minute couple and it had to be Zeno and Kuro!! I'm just gonna pretend that the manga ended when they got married for my peace of mind
