Uhhhh, I'm not entirely sure how I feel about the publication aging him down a bit and aging her up a bit (at least the art style makes it look that way), especially with her not wanting to call him her dad and the line "you're 10 years too young to be my father" at the end. Sure, it's generally an idiomatic phrase, but I'm getting some slight romance vibes as well and I'm not entirely sure that's a good change from the pre-serialization. Idk, might be reading too much into it
