Well, what did you expect? It isn't like really is that big of a deal.
To be honest, if the story would be the protagonists going like "I like him/her but... he/she is taller/shorter than me! oh no woe is me!" for dozens and dozens of chapter I would drop it super fast.
I was hoping there would be funny/sweet situations where her height plays a part. Something to that effect.
Of course it's still better that her height loses focus instead of being a big obstacle to their relationship, but it feels like the manga lost some of its charm.
